讲座预告 | Prof Michael Pecht
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 both GM and Hyunadai had to recall their EVs due to defects in the LG Chem batteries. In other cases, some companies manufacture batteries with inadequate safety features or misrepresent the true nature of their battery. 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 lecture reviews the safety issues and safety strategies for Li-ion batteries.
