What are the specifications and availability of lithium-ion batteries from a North American supply chain?

The Homeland Defense and Security Information Analysis Center (HDIAC)  received a technical inquiry requesting information on state-of-the-art battery technologies and production capabilities.

HDIAC staff found that battery technologies are actively growing. Modern patent and research approaches were submitted over the last 20 years, ranging in one to four patents submitted annually between 2001 and 2010. The research market boomed in 2011, with 18 submitted patents and a steady uptick of more, leading to 114 patents in 2020. Even with batteries as a current, hot research topic, it was discovered that there are not many North American supply chains available to public/federal agencies. Many supply chains involve foreign exports of supplies or production capabilities.

For the North American manufacturers, there are different tools utilized between the manufacturers. Some manufacturers are improving and optimizing problems that occur using today’s methods and current battery structures (mitigating heat generation in lithium-ion batteries with cathodes and anodes). Others are focusing more on battery output instead of battery life (changing the chemical composition of cathodes/anodes to generate a higher output while implementing design and engineering controls to minimize design-based drawbacks).  And some are redesigning batteries entirely from an engineering and design standpoint (using uniform Li-metal cathode technologies instead of Li-ion cathodes and current technology anodes).
