The present application relates to a battery cell, a battery, and an electric device. The battery cell comprises a casing, a cell core, a current collecting disc, and a cover plate. During assembly of the cover plate, the cover plate covers an opening of the casing, and a protruding portion of the cover plate extends into the casing from the opening. The side surface of the protruding portion abuts against positioning portions of a flange, so that the cover plate can be positioned in the radial direction. Since a welding region of the flange is located between every two adjacent positioning portions, a weld mark generated by welding the flange and the inner wall of the casing is also located between the two positioning portions. Moreover, since in the radial direction of the current collecting disc, the height of each weld mark is not higher than the height of each positioning portion, the weld mark can be prevented from abutting against the protruding portion under the support of the positioning portion, or the weld mark is just in contact with the protruding portion without affecting the abutting between the positioning portion and the protruding portion. Therefore, even if uneven weld marks are formed, the radial positioning accuracy of the cover plate is not affected, thereby improving the assembly accuracy of the battery cell.
