Abstract

The present application provides a battery cell, a battery, and an electrical apparatus, which belongs to the field of battery technologies. The battery cell includes a shell, an electrode terminal, and an electrode assembly. The shell has a wall portion. The electrode terminal is mounted on the wall portion in an insulated manner. The electrode assembly is accommodated in the shell, and the electrode assembly includes a main body part, a first tab, and a second tab. The first tab and the second tab have opposite polarities. In a thickness direction of the wall portion, the first tab and the second tab are both arranged at one end of the main body part facing the wall portion. The wall portion has a first surface facing the electrode assembly, a connecting portion is arranged to protrude from the first surface, the connecting portion is electrically connected to the first tab, and the electrode terminal is electrically connected to the second tab. This type of battery cell is conducive to optimizing the height of the first tab protruding from the main body part, and is capable of improving the contact effect between the connecting portion and the first tab, and there is no need to arrange a component of a special-shaped structure connecting the wall portion and the first tab between the wall portion and the first tab, so as to reduce the difficulty of assembling the battery cell.
