Battery and energy consumption device

Abstract

A battery characterized in that it comprises: a housing, wherein a receiving chamber is formed in the housing, the housing comprising a first wall, the first wall comprising a first inner surface facing the receiving chamber and a first outer surface facing away from the receiving chamber, the first wall having a projection, wherein a receiving groove is formed in the projection, a groove opening of the receiving groove facing the receiving chamber, an inner surface of the receiving groove comprising a first bottom surface and a first side surface, the first bottom surface facing the groove opening, the first side surface adjoining the first bottom surface; a cell pole connected to the first wall, the cell pole being offset from the projection;a cell arranged in the receiving chamber, the cell comprising a cell base body and a pole flag electrically connected to the cell base body, the pole flag and the cell pole being electrically connected via a transition plate, the transition plate being connected to the cell pole by welding to form a first weld mark, the transition plate being connected to the pole flag by welding to form a second weld mark, the pole flag and / or the transition plate being at least partially received in the receiving groove;where, along the first direction, the minimum distance between the second weld mark and the first bottom surface is h, and along the second direction, the minimum distance between an edge of the first weld mark and an edge of the second weld mark is L, where the first direction is the normal direction of the first outer surface, while the second direction is the arrangement direction of the cell pole and the receiving groove, where 1 mm² ≤ h × L ≤ 500 mm² applies.
