A battery cell, a battery, and an electrical apparatus are described. The battery cell comprises a shell, an electrode assembly, an insulating member and a support member. The electrode assembly is accommodated in the shell and comprises an electrode main body and a tab, the tab being led out from an end of the electrode main body. The insulating member is accommodated in the shell and is attached to the peripheral side surface of the electrode main body, and the insulating member is provided with an opening. The support member is used for supporting the electrode assembly and covering the opening. The battery cell provided by the present application helps to improve the deformation consistency of parts in the electrode assembly, and reduces the risk of lithium plating of the electrode assembly, thus improving the safety performance of the battery cell.
