A battery cell includes a casing with a wall portion having a weakened portion configured to rupture when internal pressure is released. The outer surface of the wall portion has a center point. A minimum distance between a projection of the weakened portion and the center point is defined as a, and a minimum radial dimension of the outer surface is defined as A, where a is greater than or equal to 0.3A. The weakened portion is positioned farther from the center and closer to the edge of the wall portion. The edge area has greater rigidity, deformation resistance, and fatigue resistance compared to the center. Placing the weakened portion near the edge reduces the likelihood of fatigue failure under gas pressure and helps prevent premature rupture, thereby improving pressure release reliability and maintaining normal battery cell operation.
