Original Abstract Submitted
A battery cell includes a housing and a pressure relief mechanism. A first through-hole is created on the housing. The pressure relief mechanism covers the first through hole. A cover sheet in the pressure relief mechanism is bonded to the housing by the adhesive film. A first passivation layer is disposed on a surface of the cover sheet. The adhesive film is meltable by heat to make the cover sheet fall off to form a pressure relief channel communicating inside and outside of the housing.
