  • Publication number: 20230299440
    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.

  • Publication number: 20230223642
    Abstract: A pressure relief apparatus, a battery cell, a battery, and an electrical device are provided in embodiments of the present application. The pressure relief apparatus includes a pressure relief body and a score groove. The pressure relief body includes a pressure relief portion configured to be opened to relieve a pressure inside the battery cell when an internal pressure or temperature of the battery cell reaches a threshold. The score groove is arranged on the pressure relief body and includes a first arc-shaped groove and a second arc-shaped groove. The arc-shaped design of the first arc-shaped groove and the second arc-shaped groove makes it less likely that the pressure relief portion cannot be opened in a large area, thereby improving the safety of the battery cell.
