Lithium-ion battery thermal runaway is a phenomenon in which the temperature of the battery suddenly and uncontrollably rises sharply, eventually leading to the explosion and burning of the battery. In the process of battery temperature rise, there are 3 characteristic temperatures, T1, T2, and T3, related to thermal runaway .
