Abstract: A housing of a battery may be produced to have a reduced flange, such that an interior volume of the housing is increased. The housing may include a can and a cover welded to one another to form a flange of the housing. The cover may be generally planar, and the can may include a curved portion and a planar portion extending from the curved portion. The planar portion may be welded to the cover to form the flange. A weld seam between the can and the cover may begin generally at an end of the planar portion of the can adjacent to the curved portion, and the flange may be cut along or adjacent to the weld seam. In particular, a distance between a transition point of the curved portion of the can and an outermost end of the flange may be less than 300 microns.
