Abstract: Battery systems according to embodiments of the present technology may include a battery including a first electrode terminal and a second electrode terminal accessible along a first surface of the battery. The battery may define a recessed portion of the battery along the first surface of the battery between the first electrode terminal and the second electrode terminal. The battery systems may include a module electrically coupled with the battery. The module may include a circuit board. The module may include a first conductive tab extending from a second surface of the circuit board opposite the first surface of the circuit board. The first conductive tab may be electrically coupling the module with the first electrode terminal. The module may include a second conductive tab extending from the second surface of the circuit board. The second conductive tab may be electrically coupling the module with the second electrode terminal.

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.
