The method comprises preparing an electrode assembly, the electrode assembly including a plurality of electrode plates, a plurality of electrode tabs, and a separator, forming a plurality of electrode leads by friction-welding a copper piece and an aluminum piece, attaching a sealing film to each of the plurality of electrode leads, packing the electrode assembly in a pouch case, with the aluminum piece exposed to an outside of the pouch case, injecting an electrolyte into the pouch case, sealing the pouch case to form each of the plurality of battery cells, stacking the plurality of battery cells one over another, and connecting the aluminum pieces of the plurality of battery cells to each other via a sensing bus bar.

Abstract: A housing for a button cell battery includes a top, a can and a grommet. The skirt of the can extends between a top panel and a free end, and includes a substantially vertical first section and an outwardly tapered second section. The first section extends from the top panel of the can. The second section extends from the first section. Upon assembly of the housing, a flow path is defined between an outer surface of the skirt of the grommet and the inner surface of the skirt of the can. The flow path allows air to escape during the assembly, thus minimizing the risk of gas being entrapped within the interior of the housing of the finished cell battery.
