Abstract: A battery cell includes: a housing; at least one wound cell arranged in the housing, where each wound cell has a tab, and the tab at at least one end forms a flattened plane covering an end surface of the wound cell; a pole; and an adapting member connecting the pole to the tab of the at least one wound cell. In the battery cell, the tab at at least one end on the wound cell forms the flattened plane covering the end surface of the wound cell, which can reduce the battery space occupied by the tab, and increase the winding space, thereby improving the energy density of the battery cell. The flattened plane can be stably connected to the adapting member, overcoming the need to align a plurality of tabs for a stable connection to the adapting plate. This improves production line efficiency and reduces battery production costs.
