BATTERY AND ELECTRIC APPARATUS

A battery includes a plurality of battery cells arranged in a first direction. The battery cell includes a first wall and a second wall that intersect, the first wall is provided with a pressure relief mechanism, and a protective member is disposed between the second wall and an inner wall of a box. The pressure relief mechanism and the protective member are disposed on two different walls of the battery cell respectively. When emissions produced by thermal runaway of the battery are discharged from the pressure relief mechanism disposed on the first wall, if some emissions fall between the second wall of the battery cell and the inner wall of the box, under the protective effect of the protective member, electrical connection between the second wall of the battery cell and the inner wall of the box can be effectively avoided, thereby reducing the risk of short circuit.
