Abstract

En 中文

• Standard single side indentation test to apply on multiple LCO, LFP and NMC cells • Prediction of cell thermal runaway severity by utilizing mechanical abuse test data. • Monitor of the transitions of electrochemical and mechanical energy into thermal energy by IR camera and AE device. • Surface temperature distributions recorded by IR camera can inform heat transfer patterns in indented LIBs. • The AE signals can serve as precursors of thermal runaway, detecting internal degradation and internal fracture of LIBs.
