These patients may require hemodialysis and extensive supports in the intensive care. Methods: A review was performed on the available literature of SILENT with a focus on current pathophysiological hypotheses and advances in treatment. Articles were restricted to the English language. Results: Although the exact mechanism is unclear, CNS demyelination, especially in the cerebellum, was seen on the brain biopsies of a proportion of patients. There is no definitive management of SILENT but instead current management is focused on primary and tertiary prevention – detection of those at risk, and rehabilitation post onset of neurological deficits. Conclusions: This review draws conclusions from a limited amount of available literature, most of which are isolated case reports. Greater awareness of SILENT and further investigation into the risk factors and pathogenesis are required so this serious and irreversible syndrome may be avoided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium%20toxicity" title="lithium toxicity">lithium toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenesis" title=" pathogenesis"> pathogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=SILENT" title=" SILENT"> SILENT</a>, <a href="https://publications.waset.org/abstracts/search?q=syndrome%20of%20irreversible%20lithium-effectuated%20neurotoxicity" title=" syndrome of irreversible lithium-effectuated neurotoxicity"> syndrome of irreversible lithium-effectuated neurotoxicity</a> </p> <a href="https://publications.waset.org/abstracts/34033/syndrome-of-irreversible-lithium-effectuated-neurotoxicity-case-report-and-review-of-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34033.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">496</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1212</span> Reuse of Spent Lithium Battery for the Production of Environmental Catalysts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jyh-Cherng%20Chen">Jyh-Cherng Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Shiang%20You"> Chih-Shiang You</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie-Shian%20Cheng"> Jie-Shian Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to recycle and reuse of spent lithium-cobalt battery and lithium-iron battery in the production of environmental catalysts. The characteristics and catalytic activities of synthesized catalysts for different air pollutants are analyzed and tested. The results show that the major metals in spent lithium-cobalt batteries are lithium 5%, cobalt 50%, nickel 3%, manganese 3% and the major metals in spent lithium-iron batteries are lithium 4%, iron 27%, and copper 4%. The catalytic activities of metal powders in the anode of spent lithium batteries are bad. With using the precipitation-oxidation method to prepare the lithium-cobalt catalysts from spent lithium-cobalt batteries, their catalytic activities for propane decomposition, CO oxidation, and NO reduction are well improved and excellent. The conversion efficiencies of the regenerated lithium-cobalt catalysts for those three gas pollutants are all above 99% even at low temperatures 200-300 °C.

Graphite is a traditional anode material that was used in almost all commercialized lithium-ion batteries. It gives a specific capacity of 372 mAh/g for lithium storage. But there are multiple better choices for storing lithium that propose significantly higher specific capacities. As an example, silicon-based materials can be mentioned. In this regard, SiO₂ material can offer a huge specific capacity of 1965 mAh/g. Due to this high lithium storage ability, large volume change occurs in this electrode material during insertion and extraction of lithium, which may lead to cracking and destruction of the electrode. The use of nanomaterials instead of bulk material can significantly solve this problem. In addition, if we insert lithium in the active material of the battery before its cycling, which is called pre-lithiation, a further enhancement in the performance is expected. Here, we have fabricated an anode electrode of the battery using SiO₂ nanomaterial mixed with Graphite and assembled a lithium-ion battery half-cell with this electrode. Next, a pre-lithiation was performed on the SiO₂ nanoparticle-containing electrode, and the resulting anode material was investigated. This electrode has great potential for high-performance lithium-ion batteries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SiO%E2%82%82%20nanoparticles" title="SiO₂ nanoparticles">SiO₂ nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title=" lithium-ion battery"> lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-lithiation" title=" pre-lithiation"> pre-lithiation</a>, <a href="https://publications.waset.org/abstracts/search?q=anode%20material" title=" anode material"> anode material</a> </p> <a href="https://publications.waset.org/abstracts/158363/pre-lithiation-of-sio2-nanoparticles-based-anode-for-lithium-ion-battery-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158363.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1210</span> Electrochemical Recovery of Lithium from Geothermal Brines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanaz%20Mosadeghsedghi">Sanaz Mosadeghsedghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathew%20Hudder"> Mathew Hudder</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ali%20Baghbanzadeh"> Mohammad Ali Baghbanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Charbel%20Atallah"> Charbel Atallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyedeh%20Laleh%20Dashtban%20Kenari"> Seyedeh Laleh Dashtban Kenari</a>, <a href="https://publications.waset.org/abstracts/search?q=Konstantin%20Volchek"> Konstantin Volchek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lithium has recently been extensively used in lithium-ion batteries (LIBs) for electric vehicles and portable electronic devices. The conventional evaporative approach to recover and concentrate lithium is extremely slow and may take 10-24 months to concentrate lithium from dilute sources, such as geothermal brines. To response to the increasing industrial lithium demand, alternative extraction and concentration technologies should be developed to recover lithium from brines with low concentrations. In this study, a combination of electrocoagulation (EC) and electrodialysis (ED) was evaluated for the recovery of lithium from geothermal brines. The brine samples in this study, collected in Western Canada, had lithium concentrations of 50-75 mg/L on a background of much higher (over 10,000 times) concentrations of sodium. This very high sodium-to-lithium ratio poses challenges to the conventional direct-lithium extraction processes which employ lithium-selective adsorbents. EC was used to co-precipitate lithium using a sacrificial aluminium electrode. The precipitate was then dissolved, and the leachate was treated using ED to separate and concentrate lithium from other ions. The focus of this paper is on the study of ED, including a two-step ED process that included a mono-valent selective stage to separate lithium from multi-valent cations followed by a bipolar ED stage to convert lithium chloride (LiCl) to LiOH product. Eventually, the ED cell was reconfigured using mono-valent cation exchange with the bipolar membranes to combine the two ED steps in one. Using this process at optimum conditions, over 95% of the co-existing cations were removed and the purity of lithium increased to over 90% in the final product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20separation" title="electrochemical separation">electrochemical separation</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title=" electrocoagulation"> electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodialysis" title=" electrodialysis"> electrodialysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20extraction" title=" lithium extraction"> lithium extraction</a> </p> <a href="https://publications.waset.org/abstracts/175784/electrochemical-recovery-of-lithium-from-geothermal-brines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175784.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1209</span> Investigating the Influence of Potassium Ion Doping on Lithium-Ion Battery Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liyew%20Yizengaw%20Yitayih">Liyew Yizengaw Yitayih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This nanotechnology study focuses on how potassium ions (K+) affect lithium-ion (Li-ion) battery performance. By adding potassium ions (K+) to the lithium tin oxide (LiSnO) anode and employing styrene-butadiene rubber (SBR) as a binder, the doping of K+ was specifically studied. The methods employed in this study include computer modeling and simulation, material fabrication, and electrochemical characterization. The potassium ions (Li+) were successfully doped into the LiSnO lattice during charge/discharge cycles, which increased the lithium-ion diffusivity and electrical conductivity within the anode. However, it was found that internal doping of potassium ions (K+) into the LiSnO lattice occurred at high potassium ion concentrations (>16.6%), which hampered lithium ion transfer because of repulsion and physical blockage. The electrochemical efficiency of lithium-ion batteries was improved by this comprehensive study's presentation of potassium ions' (K+) potential advantages when present in the appropriate concentrations in electrode materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title="lithium-ion battery">lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=LiSnO%20anode" title=" LiSnO anode"> LiSnO anode</a>, <a href="https://publications.waset.org/abstracts/search?q=potassium%20doping" title=" potassium doping"> potassium doping</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20diffusivity" title=" lithium-ion diffusivity"> lithium-ion diffusivity</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20conductivity" title=" electronic conductivity"> electronic conductivity</a> </p> <a href="https://publications.waset.org/abstracts/173540/investigating-the-influence-of-potassium-ion-doping-on-lithium-ion-battery-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173540.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1208</span> Stabilizing of Lithium-Solid-Electrolyte Interfaces by Atomic Layer Deposition Prepared Nano-Interlayers for a Model All-Solid-State Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rainer%20Goetz">Rainer Goetz</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Ahaliabadeh"> Zahra Ahaliabadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Princess%20S.%20Llanos"> Princess S.

A model battery is needed whose characterization is independent of the influence of the complex battery assembly. Lithium-Ion Conducting Glass-Ceramic (LICGC), a model solid electrolyte, is chosen for its stability in the air, but on the other hand, it is also well-known for its instability against metallic lithium upon direct contact. Hence, as a first step towards a model ASSB, the interface between lithium and the solid electrolyte (SE) is stabilized with thin (5 nm and 10 nm) coatings of titanium oxide (TO) and lithium titanium oxide (LTO). Impedance data shows that both materials are able to protect the SE surface from rapid degradation due to reducing lithium and, therefore, can serve as a protective interlayer on the anode side of a model ASSB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=all-solid-state%20battery" title="all-solid-state battery">all-solid-state battery</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20anode" title=" lithium anode"> lithium anode</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20electrolytes" title=" solid electrolytes"> solid electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=interlayers" title=" interlayers"> interlayers</a> </p> <a href="https://publications.waset.org/abstracts/163463/stabilizing-of-lithium-solid-electrolyte-interfaces-by-atomic-layer-deposition-prepared-nano-interlayers-for-a-model-all-solid-state-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163463.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1207</span> Membranes for Direct Lithium Extraction (DLE)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Razmjou">Amir Razmjou</a>, <a href="https://publications.waset.org/abstracts/search?q=Elika%20Karbassi%20Yazdi"> Elika Karbassi Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several direct lithium extraction (DLE) technologies have been developed for Li extraction from different brines. Although laboratory studies showed that they can technically recover Li to 90%, challenges still remain in developing a sustainable process that can serve as a foundation for the lithium dependent low-carbon economy. There is a continuing quest for DLE technologies that do not need extensive pre-treatments, fewer materials, and have simplified extraction processes with high Li selectivity. Here, an overview of DLE technologies will be provided with an emphasis on the basic principles of the materials’ design for the development of membranes with nanochannels and nanopores with Li ion selectivity. We have used a variety of building blocks such as nano-clay, organic frameworks, Graphene/oxide, MXene, etc., to fabricate the membranes. Molecular dynamic simulation (MD) and density functional theory (DFT) were used to reveal new mechanisms by which high Li selectivity was obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium%20recovery" title="lithium recovery">lithium recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane" title=" membrane"> membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20selectivity" title=" lithium selectivity"> lithium selectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=decarbonization" title=" decarbonization"> decarbonization</a> </p> <a href="https://publications.waset.org/abstracts/149229/membranes-for-direct-lithium-extraction-dle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149229.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1206</span> Assessing Lithium Recovery from Secondary Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20A.%20Santos">Carolina A.

Europe has been addressing these problems, namely through the Green Deal, with the use of batteries in mobility and energy fields. However, these require the use of critical raw materials, like lithium, which demand is estimated to grow 60 times in the next 30 years. Thus, it is fundamental to promote a circular economy with lithium recovery from secondary resources. These are nowadays key topics, which will be even more relevant in the future, so a new way to approach them is needed and must be encouraged. Therefore, one of our main goals is to analyse two methods of lithium retrieval from secondary sources, bioleaching, and electrodialysis, and assess them regarding their sustainability.

In order to overcome this limitation, a new material technology is necessary to overcome this limitation. The proposed sole lithium-air battery seems to be far behind in terms of practical implementation. In this paper, experimental analysis using COMSOL multiphysics has been conducted to predict the performance of lithium ion battery with variation in the elastic property of five different cathode materials including; LiMn2O4, LiFePO4, LiCoO2, LiV6O13, and LiTiS2. Combining LiCoO2, and aqueous lithium showed great improvement in the energy density. Thus, the material combination of LiCoO2/aqueous lithium-air could give a practical solution in achieving high energy density for application in the electric vehicle industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20energy" title="battery energy">battery energy</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20density" title=" energy density"> energy density</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion" title=" lithium-ion"> lithium-ion</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20property" title=" mechanical property"> mechanical property</a> </p> <a href="https://publications.waset.org/abstracts/124357/material-mechanical-property-for-improving-the-energy-density-of-lithium-ion-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124357.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1204</span> Simulation of Stress in Graphite Anode of Lithium-Ion Battery: Intra and Inter-Particle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wenxin%20Mei">Wenxin Mei</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinhua%20Sun"> Jinhua Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingsong%20Wang"> Qingsong Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The volume expansion of lithium-ion batteries is mainly induced by intercalation induced stress within the negative electrode, resulting in capacity degradation and even battery failure. Stress generation due to lithium intercalation into graphite particles is investigated based on an electrochemical-mechanical model in this work. The two-dimensional model presented is fully coupled, inclusive of the impacts of intercalation-induced stress, stress-induced intercalation, to evaluate the lithium concentration, stress generation, and displacement intra and inter-particle. The results show that the distribution of lithium concentration and stress exhibits an analogous pattern, which reflects the relation between lithium diffusion and stress. The results of inter-particle stress indicate that larger Von-Mises stress is displayed where the two particles are in contact with each other, and deformation at the edge of particles is also observed, predicting fracture. Additionally, the maximum inter-particle stress at the end of lithium intercalation is nearly ten times the intraparticle stress. And the maximum inter-particle displacement is increased by 24% compared to the single-particle. Finally, the effect of graphite particle arrangement on inter-particle stress is studied. It is found that inter-particle stress with tighter arrangement exhibits lower stress. This work can provide guidance for predicting the intra and inter-particle stress to take measures to avoid cracking of electrode material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical-mechanical%20model" title="electrochemical-mechanical model">electrochemical-mechanical model</a>, <a href="https://publications.waset.org/abstracts/search?q=graphite%20particle" title=" graphite particle"> graphite particle</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20concentration" title=" lithium concentration"> lithium concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20ion%20battery" title=" lithium ion battery"> lithium ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/128469/simulation-of-stress-in-graphite-anode-of-lithium-ion-battery-intra-and-inter-particle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128469.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1203</span> Thermochemical Modelling for Extraction of Lithium from Spodumene and Prediction of Promising Reagents for the Roasting Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Allen%20Yushark%20Fosu">Allen Yushark Fosu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ndue%20Kanari"> Ndue Kanari</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Vaughan"> James Vaughan</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Changes"> Alexandre Changes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spodumene is a lithium-bearing mineral of great interest due to increasing demand of lithium in emerging electric and hybrid vehicles. The conventional method of processing the mineral for the metal requires inevitable thermal transformation of α-phase to the β-phase followed by roasting with suitable reagents to produce lithium salts for downstream processes. The selection of appropriate reagent for roasting is key for the success of the process and overall lithium recovery. Several researches have been conducted to identify good reagents for the process efficiency, leading to sulfation, alkaline, chlorination, fluorination, and carbonizing as the methods of lithium recovery from the mineral.HSC Chemistry is a thermochemical software that can be used to model metallurgical process feasibility and predict possible reaction products prior to experimental investigation. The software was employed to investigate and explain the various reagent characteristics as employed in literature during spodumene roasting up to 1200°C. The simulation indicated that all used reagents for sulfation and alkaline were feasible in the direction of lithium salt production. Chlorination was only feasible when Cl2 and CaCl2 were used as chlorination agents but not NaCl nor KCl. Depending on the kind of lithium salt formed during carbonizing and fluorination, the process was either spontaneous or nonspontaneous throughout the temperature range investigated. The HSC software was further used to simulate and predict some promising reagents which may be equally good for roasting the mineral for efficient lithium extraction but have not yet been considered by researchers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermochemical%20modelling" title="thermochemical modelling">thermochemical modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=HSC%20chemistry%20software" title=" HSC chemistry software"> HSC chemistry software</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium" title=" lithium"> lithium</a>, <a href="https://publications.waset.org/abstracts/search?q=spodumene" title=" spodumene"> spodumene</a>, <a href="https://publications.waset.org/abstracts/search?q=roasting" title=" roasting"> roasting</a> </p> <a href="https://publications.waset.org/abstracts/144068/thermochemical-modelling-for-extraction-of-lithium-from-spodumene-and-prediction-of-promising-reagents-for-the-roasting-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144068.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1202</span> Study of the Hydrodynamic of Electrochemical Ion Pumping for Lithium Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Sofia%20Palagonia">Maria Sofia Palagonia</a>, <a href="https://publications.waset.org/abstracts/search?q=Doriano%20Brogioli"> Doriano Brogioli</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabio%20La%20Mantia"> Fabio La Mantia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last decade, lithium has become an important raw material in various sectors, in particular for rechargeable batteries. Its production is expected to grow more and more in the future, especially for mobile energy storage and electromobility. Until now it is mostly produced by the evaporation of water from salt lakes, which led to a huge water consumption, a large amount of waste produced and a strong environmental impact. A new, clean and faster electrochemical technique to recover lithium has been recently proposed: electrochemical ion pumping. It consists in capturing lithium ions from a feed solution by intercalation in a lithium-selective material, followed by releasing them into a recovery solution; both steps are driven by the passage of a current. In this work, a new configuration of the electrochemical cell is presented, used to study and optimize the process of the intercalation of lithium ions through the hydrodynamic condition. Lithium Manganese Oxide (LiMn₂O₄) was used as a cathode to intercalate lithium ions selectively during the reduction, while Nickel Hexacyano Ferrate (NiHCF), used as an anode, releases positive ion. The effect of hydrodynamics on the process has been studied by conducting the experiments at various fluxes of the electrolyte through the electrodes, in terms of charge circulated through the cell, captured lithium per unit mass of material and overvoltage. The result shows that flowing the electrolyte inside the cell improves the lithium capture, in particular at low lithium concentration. Indeed, in Atacama feed solution, at 40 mM of lithium, the amount of lithium captured does not increase considerably with the flux of the electrolyte. Instead, when the concentration of the lithium ions is 5 mM, the amount of captured lithium in a single capture cycle increases by increasing the flux, thus leading to the conclusion that the slowest step in the process is the transport of the lithium ion in the liquid phase. Furthermore, an influence of the concentration of other cations in solution on the process performance was observed. In particular, the capturing of the lithium using a different concentration of NaCl together with 5 mM of LiCl was performed, and the results show that the presence of NaCl limits the amount of the captured lithium. Further studies can be performed in order to understand why the full capacity of the material is not reached at the highest flow rate. This is probably due to the porous structure of the material since the liquid phase is likely not affected by the convection flow inside the pores. This work proves that electrochemical ion pumping, with a suitable hydrodynamic design, enables the recovery of lithium from feed solutions at the lower concentration than the sources that are currently exploited, down to 1 mM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desalination%20battery" title="desalination battery">desalination battery</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20ion%20pumping" title=" electrochemical ion pumping"> electrochemical ion pumping</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic" title=" hydrodynamic"> hydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium" title=" lithium"> lithium</a> </p> <a href="https://publications.waset.org/abstracts/67174/study-of-the-hydrodynamic-of-electrochemical-ion-pumping-for-lithium-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67174.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">208</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1201</span> Evaluating the Durability and Safety of Lithium-Ion Batterie in High-Temperature Desert Climates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kenza%20Maher">Kenza Maher</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Zakaria"> Yahya Zakaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Noora%20S.%20Al-Jaidah"> Noora S.

In this study, four commercially available 18650 lithium-ion cells from four different manufacturers are subjected to accelerated cycle aging for up to 500 cycles at two different temperatures (25°C and 45°C). The cells are also calendar-aged at the same temperatures in both charged and discharged states for 6 months to investigate the effect of aging and temperature on capacity fade and state of health. The results showed that all battery cells demonstrated good cyclability and had a good state of health at both temperatures. However, the capacity loss and state of health of these cells are found to be dependent on the cell chemistry and aging conditions, including temperature. Specifically, the capacity loss is found to be higher at the higher aging temperature, indicating the significant impact of temperature on the aging of lithium-ion batteries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title="lithium-ion battery">lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=aging%20mechanisms" title=" aging mechanisms"> aging mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=cycle%20aging" title=" cycle aging"> cycle aging</a>, <a href="https://publications.waset.org/abstracts/search?q=calendar%20aging." title=" calendar aging."> calendar aging.</a> </p> <a href="https://publications.waset.org/abstracts/165119/evaluating-the-durability-and-safety-of-lithium-ion-batterie-in-high-temperature-desert-climates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165119.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1200</span> Facile Synthesis of Copper Based Nanowires Suitable for Lithium Ion Battery Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeinab%20Sanaee">Zeinab Sanaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Jafaripour"> Hossein Jafaripour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Copper is an excellent conductive material that is widely used in the energy devices such as Lithium-ion batteries and supercapacitors as the current collector.

Alkaline leaching of lithium concentrates allows the establishment of a production diagram avoiding most of the environmental drawbacks that are associated with the usage of acid reagents. The tested processes involve a pretreatment by digestion at high temperatures with additives, followed by leaching at hot atmospheric pressure. The solutions obtained must be compatible with solutions from the leaching of spodumene concentrates, allowing the development of a common treatment diagram, an important accomplishment for the feasible exploitation of Portuguese resources.

The anode is derived from sulfurized polyacrylonitrile (S-C(PAN)). Severe capacity fading usually becomes unavoidable due to the oxidative decomposition of solvents, primarily when a conventional carbonate electrolyte with 1 M lithium hexafluorophosphate (LiPF6) is employed. Fluoroethylene carbonate (FEC), ethyl methyl carbonate (EMC), and 1, 1, 2, 2-Tetrafluoroethyl-2, 2, 3, 3-tetrafluoropropyl ether (TTE) are formulated as the best electrolyte (3:2:5 in vol. ratio) for this new high-voltage lithium-ion battery to mitigate this capacity fading and improve the adaptability of the S-C(PAN) and LNMO. The discharge capacity of a full cell made with 1 M lithium hexafluorophosphate (LiPF6) in FEC/EMC/TTE (3:2:5) electrolyte reaches 688 mAh g⁻¹ at a rate of 2 C, while 19 mAh g⁻¹ for the control electrolyte. X-ray photoelectron spectroscopy (XPS) results confirm that the fluorinated electrolyte effectively stabilizes both surfaces of S-C(PAN) and LNMO in the full cell. Compared to the control electrolyte, the developed electrolyte enhances the cyclic stability and rate capability of both half cells (Li//S-C(PAN and Li//LiNi₀.₅Mn₁.₅O₄) and S-C(PAN)//LiNi₀.₅Mn₁.₅O₄ full cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluorinated%20electrolyte" title="fluorinated electrolyte">fluorinated electrolyte</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20voltage" title=" high voltage"> high voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title=" lithium-ion battery"> lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=polyacrylonitrile" title=" polyacrylonitrile"> polyacrylonitrile</a> </p> <a href="https://publications.waset.org/abstracts/193157/partially-fluorinated-electrolyte-for-high-voltage-cathode-for-lithium-ion-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">13</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1193</span> Synthesis of SnO Novel Cabbage Nanostructure and Its Electrochemical Property as an Anode Material for Lithium Ion Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yongkui%20Cui">Yongkui Cui</a>, <a href="https://publications.waset.org/abstracts/search?q=Fengping%20Wang"> Fengping Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hailei%20Zhao"> Hailei Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zubair%20Iqbal"> Muhammad Zubair Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziya%20Wang"> Ziya Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Li"> Yan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Pengpeng%20LV"> Pengpeng LV</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The novel 3D SnO cabbages self-assembled by nanosheets were successfully synthesized via template-free hydrothermal growth method under facile conditions.The XRD results manifest that the as-prepared SnO is tetragonal phase.

Current global demand for lithium, estimated at 0.95-0.98 million metric tons (Mt) of lithium carbonate equivalent (LCE) annually in 2024, is projected to rise to 1.87 Mt by 2027 and 3.06 Mt by 2030. Despite anticipated short-term stability in supply and demand, meeting the forecasted 2030 demand will require the lithium industry to develop an additional capacity of 1.42 Mt of LCE annually, exceeding current planned and ongoing efforts. Brine resources constitute nearly 65% of global lithium reserves, underscoring the importance of exploring lithium recovery from underutilized sources, especially geothermal brines. However, conventional lithium extraction from brine deposits faces challenges due to its time-intensive process, low efficiency (30-50% lithium recovery), unsuitability for low lithium concentrations (<300 mg/l), and notable environmental impacts. Addressing these challenges, direct lithium extraction (DLE) methods have emerged as promising technologies capable of economically extracting lithium even from low-concentration brines (>50 mg/l) with high recovery rates (75-98%). However, most studies (70%) have predominantly focused on synthetic brines instead of native (natural/real), with limited application of these approaches in real-world case studies or industrial settings. This study aims to bridge this gap by investigating a geothermal brine sample collected from a real case study site in the UK. A Mn-based lithium-ion sieve (LIS) adsorbent was synthesized and employed to selectively extract lithium from the sample brine. Adsorbents with a Li:Mn molar ratio of 1:1 demonstrated superior lithium selectivity and adsorption capacity. Furthermore, the pristine Mn-based adsorbent was modified through transition metals doping, resulting in enhanced lithium selectivity and adsorption capacity. The modified adsorbent exhibited a higher separation factor for lithium over major co-existing cations such as Ca, Mg, Na, and K, with separation factors exceeding 200. The adsorption behaviour was well-described by the Langmuir model, indicating monolayer adsorption, and the kinetics followed a pseudo-second-order mechanism, suggesting chemisorption at the solid surface. Thermodynamically, negative ΔG° values and positive ΔH° and ΔS° values were observed, indicating the spontaneity and endothermic nature of the adsorption process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20minerals" title=" critical minerals"> critical minerals</a>, <a href="https://publications.waset.org/abstracts/search?q=DLE" title=" DLE"> DLE</a>, <a href="https://publications.waset.org/abstracts/search?q=geothermal%20brines" title=" geothermal brines"> geothermal brines</a>, <a href="https://publications.waset.org/abstracts/search?q=geochemistry" title=" geochemistry"> geochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium" title=" lithium"> lithium</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20sieves" title=" lithium-ion sieves"> lithium-ion sieves</a> </p> <a href="https://publications.waset.org/abstracts/186911/selective-extraction-of-lithium-from-native-geothermal-brines-using-lithium-ion-sieves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186911.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">46</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1191</span> Evaluation of a Reconditioning Procedure for Batteries: Case Study on Li-Ion Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.-A.%20Ciobotaru">I.-A.

Efforts have been focused on the recycling of batteries; however, extending their lifetime may be a more adequate alternative, and the development of such methods may prove to be more cost efficient as compared to recycling. In this context, this paper presents the analysis of a proposed process for the reconditioning of some lithium-ions batteries. The analysis is performed based on two criteria, the first one referring to the technical aspect of the reconditioning process and the second to the economic aspects. The main technical parameters taken into consideration are the values of capacitance and internal resistance of the lithium-ion batteries. The economic criterion refers to the evaluation of the efficiency of the reconditioning procedure reported to its total cost for the investigated lithium-ion batteries. Based on the cost analysis, one introduced a novel coefficient that correlates the efficiency of the aforementioned process and its corresponding costs. The reconditioning procedure for the lithium-ion batteries proposed in this paper proved to be valid, efficient, and with reasonable costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost%20assessment" title="cost assessment">cost assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title=" lithium-ion battery"> lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=reconditioning%20coefficient" title=" reconditioning coefficient"> reconditioning coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=reconditioning%20procedure" title=" reconditioning procedure"> reconditioning procedure</a> </p> <a href="https://publications.waset.org/abstracts/111288/evaluation-of-a-reconditioning-procedure-for-batteries-case-study-on-li-ion-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1190</span> Gamma-Hydroxybutyrate (GHB): A Review for the Prehospital Clinician</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Theo%20Welch">Theo Welch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Gamma-hydroxybutyrate (GHB) is a depressant of the central nervous system with euphoric effects.

Methods: A literature review was undertaken of its pharmacology and the emergency management of its acute toxicity.Findings: GHB is inexpensive and readily available over the Internet. Treatment of GHB acute toxicity is supportive. Clinicians should pay particular attention to the airway as emesis is common. Intubation is required in a minority of cases. Polydrug use is common and worsens prognosis. Conclusion: An inexpensive and readily available drug, GHB acute toxicity can be difficult to identify and treat.

A promising strategy involves transforming lithium-ion batteries into hybrid configurations by integrating lithium-ion and lithium-metal solid-state components. This study is focused on achieving stable lithium deposition and advancing the electrochemical capabilities of solid-state lithium hybrid batteries with anodes by incorporating mesocarbon microbeads (MCMBs) blended with silver nanoparticles. To achieve this, mesocarbon microbeads (MCMBs) blended with silver nanoparticles are coated on stainless-steel current collectors. These samples undergo a battery of analyses employing diverse techniques. Surface morphology is studied through scanning electron microscopy (SEM). The electrochemical behavior of the coated samples is evaluated in both half-cell and full-cell setups utilizing an argyrodite-type sulfide electrolyte. The stability of MCMBs in the electrolyte is assessed using electrochemical impedance spectroscopy (EIS). Additional insights into the composition are gleaned through X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and energy-dispersive X-ray spectroscopy (EDS). At an ultra-low N/P ratio of 0.26, stability is upheld for over 100 charge/discharge cycles in half-cells. When applied in a full-cell configuration, the hybrid anode preserves 60.1% of its capacity after 80 cycles at 0.3 C under a low N/P ratio of 0.45. In sharp contrast, the capacity retention of the cell using untreated MCMBs declines to 20.2% after a mere 60 cycles. The introduction of mesocarbon microbeads (MCMBs) combined with silver nanoparticles into the hybrid anode of solid-state lithium batteries substantially elevates their stability and electrochemical performance. This approach ensures consistent lithium deposition and removal, mitigating dendrite growth and the accumulation of inactive lithium. The findings from this investigation hold significant value in elevating the reversibility and energy density of lithium-ion batteries, thereby making noteworthy contributions to the advancement of more efficient energy storage systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MCMB" title="MCMB">MCMB</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20metal" title=" lithium metal"> lithium metal</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20anode" title=" hybrid anode"> hybrid anode</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticle" title=" silver nanoparticle"> silver nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=cycling%20stability" title=" cycling stability"> cycling stability</a> </p> <a href="https://publications.waset.org/abstracts/171703/mesocarbon-microbeads-modification-of-stainless-steel-current-collector-to-stabilize-lithium-deposition-and-improve-the-electrochemical-performance-of-anode-solid-state-lithium-hybrid-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171703.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1188</span> Electrode Performance of Carbon Coated Nanograined LiFePO4 in Lithium Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Princess%20Stephanie%20P.%20Llanos">Princess Stephanie P.

The X-ray diffraction pattern of the synthesized samples can be indexed to an orthorhombic LiFePO4 structure. Agglomerated particles that range from 200 nm to 300 nm are observed from scanning electron microscopy images.

Elemental mapping using Energy dispersive spectroscopy analysis revealed the homogeneous dispersion of Fe, P, O, and C elements. On the other hand, the electrochemical performances of the synthesized cathodes were investigated using cyclic voltammetry, galvanostatic charge/discharge tests with different C-rates, and cycling performances.

This technology is now mature, although there are still many challenges to increase their energy density while ensuring an irreproachable safety of use. For this goal, it is necessary to develop new cathodic materials that can be cycled at higher voltages and electrolytes compatible with these materials. But the challenge does not only concern the production of efficient batteries for the electrochemical storage of energy since lithium-ion battery technology relies on the use of critical and/or strategic value resources. It is, therefore, crucial to include Lithium-ion batteries development in a circular economy approach very early. In particular, optimized recycling and reuse of battery components must both minimize their impact on the environment and limit geopolitical issues related to tensions on the mineral resources necessary for lithium-ion battery production. Although recycling will never replace mining, it reduces resource dependence by ensuring the presence of exploitable resources in the territory, which is particularly important for countries like France, where exploited or exploitable resources are limited. This conference addresses the development of a new hydrometallurgical process combining leaching of cathodic material from spent lithium-ion battery in acidic chloride media and solvent extraction process. Most of recycling processes reported in the literature rely on the sulphate route, and a few studies investigate the potentialities of the chloride route despite many advantages and the possibility to develop new chemistry, which could get easier the metal separation. The leaching mechanisms and the solvent extraction equilibria will be presented in this conference. Based on the comprehension of the physicochemistry of leaching and solvent extraction, the present study will introduce a new hydrometallurgical process for the production of cobalt, nickel, manganese and lithium from spent cathodic materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title="lithium-ion battery">lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrometallurgy" title=" hydrometallurgy"> hydrometallurgy</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction" title=" solvent extraction"> solvent extraction</a> </p> <a href="https://publications.waset.org/abstracts/167940/investigation-of-the-physicochemistry-in-leaching-of-blackmass-for-the-recovery-of-metals-from-spent-lithium-ion-battery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167940.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1186</span> Hydrometallurgical Recovery of Cobalt, Nickel, Lithium, and Manganese from Spent Lithium-Ion Batteries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20K.%20Hardwick">E.

The applications include electric vehicles, cell phones, laptops, and many more devices. Typical components of the cathodes include lithium, cobalt, nickel, and manganese. Recycling the spent LiBs is necessary to reduce the ecological footprint of their production and use and to have a secondary source of valuable metals. A hydrometallurgical method was investigated for the recovery of cobalt and nickel from LiB cathodes. The cathodes were leached using a chloride solution. Ion exchange was then used to recover the chloro-complexes of the metals. The aim of the research was to determine the efficiency of a chloride leach, as well as ion exchange operating capacities that can be achieved for LiB recycling, and to establish the optimal operating conditions (ideal pH, temperature, leachate and eluant, flowrate, and reagent concentrations) for the recovery of the cathode metals. It was found that the leaching of the cathodes could be hindered by the formation of refractory metal oxides of cathode components. A reducing agent was necessary to improve the leaching rate and efficiency. Leaching was achieved using various chloride-containing solutions. The chloro-complexes were absorbed by the ion exchange resin and eluted to produce concentrated cobalt, nickel, lithium, and manganese streams. Chromatographic separation of these elements was achieved. Further work is currently underway to determine the optimal operating conditions for the recovery by ion exchange. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cobalt" title="cobalt">cobalt</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange" title=" ion exchange"> ion exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=leachate%20formation" title=" leachate formation"> leachate formation</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20batteries" title=" lithium-ion batteries"> lithium-ion batteries</a>, <a href="https://publications.waset.org/abstracts/search?q=manganese" title=" manganese"> manganese</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel" title=" nickel"> nickel</a> </p> <a href="https://publications.waset.org/abstracts/150918/hydrometallurgical-recovery-of-cobalt-nickel-lithium-and-manganese-from-spent-lithium-ion-batteries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150918.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1185</span> Increased Energy Efficiency and Improved Product Quality in Processing of Lithium Bearing Ores by Applying Fluidized-Bed Calcination Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edgar%20Gasafi">Edgar Gasafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Pardemann"> Robert Pardemann</a>, <a href="https://publications.waset.org/abstracts/search?q=Linus%20Perander"> Linus Perander</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the production of lithium carbonate or hydroxide out of lithium bearing ores, a thermal activation (calcination/decrepitation) is required for the phase transition in the mineral to enable an acid respectively soda leaching in the downstream hydrometallurgical section. In this paper, traditional processing in Lithium industry is reviewed, and opportunities to reduce energy consumption and improve product quality and recovery rate will be discussed. The conventional process approach is still based on rotary kiln calcination, a technology in use since the early days of lithium ore processing, albeit not significantly further developed since. A new technology, at least for the Lithium industry, is fluidized bed calcination. Decrepitation of lithium ore was investigated at Outotec’s Frankfurt Research Centre. Focusing on fluidized bed technology, a study of major process parameters (temperature and residence time) was performed at laboratory and larger bench scale aiming for optimal product quality for subsequent processing. The technical feasibility was confirmed for optimal process conditions on pilot scale (400 kg/h feed input) providing the basis for industrial process design. Based on experimental results, a comprehensive Aspen Plus flow sheet simulation was developed to quantify mass and energy flow for the rotary kiln and fluidized bed system. Results show a significant reduction in energy consumption and improved process performance in terms of temperature profile, product quality and plant footprint. The major conclusion is that a substantial reduction of energy consumption can be achieved in processing Lithium bearing ores by using fluidized bed based systems. At the same time and different from rotary kiln process, an accurate temperature and residence time control is ensured in fluidized-bed systems leading to a homogenous temperature profile in the reactor which prevents overheating and sintering of the solids and results in uniform product quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcination" title="calcination">calcination</a>, <a href="https://publications.waset.org/abstracts/search?q=decrepitation" title=" decrepitation"> decrepitation</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized%20bed" title=" fluidized bed"> fluidized bed</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium" title=" lithium"> lithium</a>, <a href="https://publications.waset.org/abstracts/search?q=spodumene" title=" spodumene"> spodumene</a> </p> <a href="https://publications.waset.org/abstracts/54838/increased-energy-efficiency-and-improved-product-quality-in-processing-of-lithium-bearing-ores-by-applying-fluidized-bed-calcination-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54838.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">230</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1184</span> The Efficacy of Lithium vs. Valporate on Bipolar Patients and Their Sexual Side Effect: A Meta-Analysis of 4159 Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasmeen%20Jamal%20Alabdallat">Yasmeen Jamal Alabdallat</a>, <a href="https://publications.waset.org/abstracts/search?q=Almutazballlah%20Bassam%20Qablan"> Almutazballlah Bassam Qablan</a>, <a href="https://publications.waset.org/abstracts/search?q=Obada%20Ahmad%20Al%20Jayyousi"> Obada Ahmad Al Jayyousi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ihdaa%20Mahmoud%20Bani%20Khalaf"> Ihdaa Mahmoud Bani Khalaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20E.%20Alshial"> Eman E. Alshial</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Bipolar disorder, formerly known as manic depression, is a mental health status that leads to extreme mood swings that include emotional lows (depression) and highs (mania or hypomania). This systematic review and meta-analysis aimed to assess the safety and efficacy of lithium versus valproate among bipolar patients. Methods: A computer literature search of PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials was conducted from inception until June 2022. Studies comparing lithium versus valproate among bipolar patients were selected for the analysis, and all relevant outcomes were pooled in the meta-analysis using Review Manager Software. Results: 11 Randomized Clinical Trials were included in this meta-analysis with a total of 4159 patients. Our meta showed that lithium was superior to valproate in terms of Young Mania Rating Scale (YMRS) (MD = 0.00 with 95% CI, (-0.55 – 0.55; I2 = 0%), P = 1.00). The results of the Hamilton Depression Rating Scale (HDRS) showed that the overall effect favored the valproate treated group (MD = 1.41 with 95% CI, (-0.15 – 2.67; I2 = 0%), P = 0.03). Concerning the results of the Montgomery-Asberg Depression Rating Scale (MADRS), the results showed that the lithium was superior to valproate (MD = 0.03 with 95% CI, (-0.80 to 0.87; I2 = 40%), P = 0.94). In terms of the sexual side effect, we found that the valproate was superior to lithium (RR 1.19 with 95% CI, (0.74 to 1.91; I2 = 0%), P = 0.47). The lithium-treated group was superior in comparison to valproate treated group in terms of Abnormal Involuntary Movement Scale (AIMS) (MD = -0.03 with 95% CI (-0.38 to 0.32; I2 = 0%), P = 0.87). The lithium was more favorable in terms of Simpson-Agnes scale (MD = -0.40 with 95% CI, (-0.86 to 0.06; I2 = 0%), P = 0.09). The results of the Barnes akathisia scale showed that the overall effect of the valproate was more favorable in comparison to lithium (MD = 0.05 with 95% CI, (-0.12 to 0.22; I2 = 0%), P = 0.57). Conclusion: Our study revealed that on the scales of efficacy Lithium treated group surpassed Valproate treated group in terms of Young Mania Rating Scale (YMRS), Abnormal Involuntary Movement Scale (AIMS) and Simpson-Agnes scale, but valproate surpassed it in Barnes Akathisia scale. Furthermore, on the scales of depression Hamilton Depression Rating Scale (HDRS) showed that the overall effect favored Valproate treated group, but Lithium surpassed valproate in terms of Montgomery-Asberg Depression Rating Scale (MADRS). Valproate surpassed Lithium in terms of sexual side effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bipolar"
