Abstract

We investigate the effects of thermally sensitive binder (TSB) on the temperature increase of lithium-ion battery (LIB) coin cell subjected to severe mechanical abuse. The TSB is poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP), similar to conventional poly(vinylidenefluoride) (PVDF) binder but with a significant hexafluoropropylene (HFP) content. The testing data show that by using TSB, the peak temperature increase of nail-penetrated LIB coin cell can be reduced by 20% to 40%, attributed to the softening of TSB that begins from ~80°C. The cycling performance of the LIB cells is also characterized. This research sheds light on the development of thermal-runaway mitigation techniques.
