Abstract: 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.

Abstract: Batteries and an electric apparatus are disclosed. The battery includes: a plurality of battery cells arranged in a first direction; an end plate disposed at an end of the plurality of battery cells in the first direction; and an insulating member for connecting with the end plate, where the insulating member is arranged on the top surface of the end plate in a second direction, the second direction being perpendicular to the first direction; where the insulating member has a maximum length A in a third direction, the end plate has a maximum length B in the third direction, where A≥0.9B and the third direction is perpendicular to the first direction and the second direction. The battery provides strength and insulation requirements on the end plate in normal use of the battery, but also reduces risks of high voltage short circuit in thermal runaway of the battery.
