The battery cell includes a shell, the shell has a wall portion, the wall portion includes a weak portion, and the weak portion is configured to be destroyed when the battery cell releases internal pressure. An outer surface of the wall portion has a center point. A maximum distance between a projection of the weak portion on the outer surface of the wall portion and the center point is a, the minimum radial dimension of the outer surface of the wall portion is A, and a and A satisfy: a≤0.4A. By setting a≤0.4A, the weak portion is arranged at a region, with a relatively low stiffness, of the wall portion. When the battery cell releases the internal pressure, the region undergoes a large deformation under the action of gas, and therefore the weak portion arranged at the region is easily damaged.
