Abstract: The safety performance of lithium-ion batteries can be evaluated on the basis of calorimetric analysis on thermal runaway process. The heat release rate and accumulative heat release of the battery at different temperatures are the parameters to measure the thermal stability of the battery. Calorimetric analysis of large-format batteries is generally carried out by adiabatic rate calorimeter (ARC). This paper mainly introduces the testing principle and method of ARC, data analysis and safety evaluation.

Key words: safety, lithium ion batteries, thermal runaway, calorimetric analysis, evaluation
