Abstract

The invention relates to a battery cell (10) having a cell housing (12) which comprises a housing container (14) and a housing cover (16), two electrodes that are arranged in an inner region of the housing container (14), an electrolyte material that is arranged in the inner region of the housing container (14) and that surrounds the electrodes, and two electrical contacts which in each case are electrically coupled to one of the electrodes and which extend from the inner region of the housing container (14) through the housing cover (16) into a region outside of the cell housing (12), wherein the housing cover (16) has an overlap area (18) at an outer edge, in which overlap area the housing cover (16) and an edge region of the housing container (14) are arranged parallel to each other, wherein in the overlap area (18) a flanged seam (20) is formed, in order to close the cell housing (12).
