Description

technical field [0001] The invention belongs to the technical field of battery heat dissipation and pressure relief energy recovery, and in particular relates to an explosion-proof structure, device and manufacturing method for battery heat dissipation and pressure relief energy recovery. Background technique [0002] Battery temperature is one of the important factors that affect battery life and safety. When the battery temperature is too high, it is easy to cause fire, explosion and other dangerous situations when encountering a collision. Whether it is used in mobile phones, electric vehicles or other batteries such as cameras , this problem exists. When the battery temperature is too low, the chemical reaction speed slows down. For example, lithium batteries may undergo slight material structure changes, resulting in the capacity not necessarily returning to the original state after returning to room temperature, resulting in the load capacity that can be provided canno...
