| description | The present application provides a battery cell, a battery and a power consuming device. The battery cell includes a shell and an end cap assembly, the shell being provided with an opening, and the end cap assembly including an end cap, an insulating member and an inner terminal, wherein the end cap is arranged at the opening, and a surface of the end cap close to the shell is provided with an annular protrusion extending in a circumferential direction of the end cap; the annular protrusion shrinks inwards relative to an edge of the end cap to form a flange between an outer side of the annular protrusion and the edge of the end cap; the flange is arranged on a shell wall of the shell, and the annular protrusion extends into the shell; and the insulating member is arranged in a groove enclosed by the annular protrusion, and the inner terminal is arranged on the insulating member. In the battery cell, the annular protrusion is provided on an inner surface of the end cap to form the groove to avoid taking up the space in cavity, thereby increasing the energy density of the battery cell. |
