Application of lithium-ion batteries (LIB) in electrified transportation and renewable grid is growing at a very fast pace for decarbonization of the passenger vehicles by 2035. Due to the characteristics of current LIB technologies, although rare, there is potential for thermal runaway and fires, as seen by recent fires in Tesla Model S, Chevy Bolt, and grid storage system in an Arizona Utility. Increased severity of fire incidents with more advanced energy-dense LIBs, especially cathodes with higher Ni, and anodes with silicon or lithium, is expected.
In this tutorial/seminar we will: 1.) discuss fundamental causes for safety issues leading to thermal runway and fire, 2.) review abusive behavior of cells and packs through characterization, testing, and modeling/simulations, 3.) provide overview of approaches that could reduce safety risks and detect impending failures, and 4.) provide references as a resource for accessing more information.
This tutorial/seminar is provided by Dr. Ahmad Pesaran with 25+ years’ experience in lithium-ion battery R&D including safety testing and modeling with perspectives of his participation at USABC Technical Advisory Committee. He will provide the audience with information and understanding needed to handle Li-ion battery safety in both their work at their companies and in products they deliver to the market.
