A battery cell includes a shell, an electrode terminal, and a blocking member. The shell includes a wall portion having a lead-out hole. The electrode terminal includes an insertion portion and a flange portion connected in an axial direction of the electrode terminal. The insertion portion is in the lead-out hole, the flange portion is at the side of the insertion portion away from the inside of the shell in a radial direction of the electrode terminal, an outer peripheral surface of the flange portion is partially beyond an outer peripheral surface of the insertion portion, and the electrode terminal has a recessed portion arranged in the axial direction. The blocking member blocks the recessed portion and includes a body that covers the side of the flange portion away from the insertion portion and connected to the flange portion. The battery cell is electrically connected externally through the blocking member.
