The Safety-related Challenges of Using Lithium-ion Batteries

Abstract:

Li-ion batteries are commercially successful power sources for a diverse range of applications. However, the characteristics of Li-ion batteries make them susceptible to both swelling and thermal runaway, resulting in failed products, and occasionally in fires and explosions. In some cases, defects in lithium batteries are not detected prior to use. For example, recently GM, Chysler, Hyundai and Stellantis had to recall their EVs due to defects in their batteries, which caused performance issues and in many cases, fires. In addition, there has been numerous fires of batteries in e-bikes, vaping devices, and consumer products. In other cases, some companies manufacture batteries with inadequate safety features or misrepresent the true nature of their battery by re-using, re-wrapping or counterfeiting batteries. To mitigate safety hazards prior to the occurrence of thermal runaway, various strategies have been applied for battery cells, as well as battery packages. This webinar reviews the safety issues and safety strategies for Li-ion batteries.
