1. IntroductionLIBs have been widely employed in the field of new energy vehicles and energy storage power stations operating at various altitudes because of their huge advantages, such as their long life cycles, high specific energy density, and low self-discharge rate [1,2,3]. However, under abuse conditions, including electrical abuse, thermal abuse, and mechanical abuse, LIBs may suffer from TR, one of their most important safety issues [4,5,6].
