Staff" rel="author">Ask A Scientist Staff</a> </span> <span class="post-info-date"> 04.14.2023 </span> </header><div class="entry-content"><p>The electric-vehicle revolution, driven by the necessity to decarbonize personal transportation to meet global targets for reductions in greenhouse gas emissions, is set to change the automotive industry radically. Consequently, demand for lithium-ion batteries for electric vehicles (EV) is rising rapidly. Global installed battery storage capacity is forecast to expand by 30-40% annually in the next five years — a trend that is likely to continue. It’s expected to reach 9,300 gigawatt hours (GWh) by 2030, which translates to a scale-up of about 20 times from 2020 levels.</p> <h2 id="toc-hId-2041824528">Lithium-ion battery manufacturing capacity</h2> <p>With the rise of electromobility and the consequent increase in EV manufacturing, the market for lithium-ion batteries has seen consistently high growth rates. For that reason, developing domestic battery supply chains, including battery manufacturing capacity, is becoming increasingly important as countries strive to shift away from gasoline vehicles to electric mobility. China is by far the leader in the battery race in 2022 with about 80% (about 558 GWh capacity) of global lithium-ion battery manufacturing capacity, followed by United States with only 6%, or 44 GWh (Source: <a href="https://www.spglobal.com/marketintelligence/en/news-insights/blog/top-electric-vehicle-markets-dominate-lithium-ion-battery-capacity-growth" target="_blank" rel="noopener nofollow noreferrer">S&P Global Market Intelligence</a>). European countries collectively make up for 68 GWh, or around 10% of global battery manufacturing.</p> <p>Heading toward zero emission goals the global lithium-ion manufacturing capacity is expected to more than double by 2025. While China is expected to come out on top, with estimated capacity around 65% worldwide, European countries are massively ramping up battery production. For instance, Germany’s capacity is projected to rise to 164 GWh, representing a 15-fold increase in just four years. It’s important to point out that the battery industry is evolving rapidly, and current estimates could change due to economic or political circumstances. However, it’s clear that both battery demand and manufacturing capacity are set to grow.</p> <div id="attachment_1006" style="width: 636px" class="wp-caption aligncenter"><img decoding="async" aria-describedby="caption-attachment-1006" class=" wp-image-1006" src="https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Battery-Table.jpg" alt="Table of top 10 lithium-ion battery producers" width="626" height="526" srcset="https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Battery-Table.jpg 780w, https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Battery-Table-300x252.jpg 300w, https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Battery-Table-768x645.jpg 768w" sizes="(max-width: 626px) 100vw, 626px" /><p id="caption-attachment-1006" class="wp-caption-text">Table: Top 10 countries by estimated lithium-ion battery manufacturing capacities in 2025 (Source: S&P Global Market Intelligence).</p></div> <h2></h2> <h2>Analytical requirements in quality control and monitoring</h2> <p>There are three main components of a battery: two terminals made of different chemicals (typically metals), the anode and the cathode; and the electrolyte, which separates these terminals.</p> <p>The electrolyte is a chemical medium that allows the flow of electrical charge between the cathode and anode. Increases in battery performance requires the development of new battery components as well as understanding and addressing the mechanisms that result in performance degradation with repeated charging and discharging cycles. Battery manufacturers must not only deliver consistent overall quality, but they must also deliver it throughout the manufacturing process. Quality needs to be monitored at every stage from raw materials through to cell assembly to maintain production efficiency and minimize waste. Likewise, development of new battery materials must ascertain all the critical parameters that could affect battery performance throughout the entire manufacturing process. The infographic below provides a great overview of the solutions for physical, chemical and structural analysis of cathode, anode, electrolyte and separator material and structure.</p> <div id="attachment_1008" style="width: 1191px" class="wp-caption aligncenter"><img decoding="async" aria-describedby="caption-attachment-1008" class="wp-image-1008 size-full" src="https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Analysis-Solutions.png" alt="Lithium-ion battery analysis solutions" width="1181" height="658" srcset="https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Analysis-Solutions.png 1181w, https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Analysis-Solutions-300x167.png 300w, https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Analysis-Solutions-1024x571.png 1024w, https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Analysis-Solutions-768x428.png 768w, https://www.thermofisher.com/blog/ask-a-scientist/wp-content/uploads/sites/15/2023/04/Analysis-Solutions-450x250.png 450w" sizes="(max-width: 1181px) 100vw, 1181px" /><p id="caption-attachment-1008" class="wp-caption-text">Overview of the solutions for physical, chemical and structural analysis of cathode, anode, electrolyte and separator material and structure.</p></div> <h2></h2> <h2 id="toc-hId--1365639087">Benefits of each analytical technique</h2> <p>Evaluation of batteries and battery components requires a variety of analytical methods that study materials and component surfaces at various scales.

This waste presents a number of serious challenges of scale. Nevertheless, spent batteries may also present an opportunity to recover strategic elements and critical materials for key components in electric-vehicle manufacture. Elements and materials contained in electric-vehicle batteries are not available in many nations. Access to resources is crucial in ensuring a stable supply chain. Recycled lithium-ion batteries from electric vehicles will therefore provide a valuable secondary source of materials. The recycling process is far from simple, however. This Nature publication, “<a href="https://www.nature.com/articles/s41586-019-1682-5" target="_blank" rel="noopener nofollow noreferrer">Recycling lithium-ion batteries from electric vehicles</a>,” nicely highlights challenges in lithium-ion battery recycling.</p> <h2>Additional resources</h2> <p id="toc-hId--1223087978"><a
