Liquid leakage analysis of soft-pack lithium-ion battery

Liquid leakage analysis of soft-pack lithium-ion battery

1 Comment / General / By

Introduction Efficient and reliable energy storage systems are crucial for our modern society. Lithium-ion batteries (LIBs) with excellent performance are widely used in portable electronics and electric vehicles (EVs), but frequent fires and explosions limit their further and more widespread applications. This review summarizes aspects of LIB safety and discusses the related issues, strategies, and testing standards. …
