Abstract: With the popularity of lithium-ion batteries in life and work, the safety accidents of lithium-ion batteries have increased year by year, and the safety research of lithium-ion batteries has gradually attracted the attention of the academic community. Studying the thermal safety of lithium-ion batteries can effectively analyze the internal causes of ignition and explosion of lithium-ion batteries and guide the research on the safety of lithium-ion batteries. This paper describes the sources and influencing factors of heat production during the operation of lithium-ion batteries, as well as the internal reaction and temperature corresponding to the thermal runaway of lithium-ion batteries, and summarizes the thermal characteristics of the battery when it is out of control.

Key words: lithium-ion batteries, heat production, thermal stability, thermal runaway
