Abstract
A battery pack relating to the field of batteries includes a battery module, a coolant and a battery box. The battery module and the coolant are disposed in the battery box. The battery module is at least partially immersed in the coolant. A sealing layer containing a barrier liquid is covered on the coolant. The heat generated by the battery cell which occurs thermal runaway is taken away rapidly by using the vaporization latent heat of the coolant, to thereby avoid heat accumulation and prevent propagation of thermal runaway among battery cells, thereby protecting the safety of the battery pack.
