Abstract
A battery cell is disclosed, including a housing, electrode terminals, and a protective member. The housing includes a wall portion and a fastener, where the fastener comprises a connecting portion and a pressing portion that together define a cavity. At least part of the electrode terminals is positioned within the cavity. The protective member includes a first protective portion covering the connecting portion and a second protective portion covering the pressing portion. The second protective portion extends beyond the pressing portion in a first direction. The structure reduces the likelihood of short circuits by shielding the pressing portion, thereby enhancing battery cell reliability.
