On the other hand, low-temperature storage has been recognized as an important approach to ensure the safety of lithium-ion batteries during transport [24,25]. Sunderlin et al. [26] examined the TR characteristics of batteries subjected to cryogenic freezing and found that pinpricking does not induce TR when the temperature is below −80 °C.
Thirdly, the batteries overheating can occur as a result of external or internal short circuits in the batteries due to punctures of the batteries or their compression and deformation [7, 8]. After that the batteries get overheated, a number of interrelated exothermic reactions occur in them, which heats up the batteries even more and leads to …
