BATTERY CELL, BATTERY AND ELECTRIC DEVICE

The present application discloses a battery cell, a battery, and an electrical apparatus. The battery cell of an embodiment of the present application includes a shell, an electrode terminal, an electrode assembly, and an insulating component. The electrode terminal is arranged on the shell. The electrode assembly is accommodated in the shell and includes a tab connected to the electrode terminal. The insulating component connects the electrode terminal and the shell and is used for insulating and separating the electrode terminal from the shell. The insulating component can not only insulate and separate the electrode terminal from the shell, but also connect the shell and the electrode terminal, thereby achieving insulation and fixation between the electrode terminal and the shell at the same time, so as to simplify the structure of the battery cell and improve the energy density of the battery cell.
