ABSTRACT:
The outside edges of a sealing plate are weld attached to close off an opening in a metal case of a prismatic battery of this invention. The sealing plate has an electrode rivet which passes through an electrode hole and sandwiches an insulating gasket to attach in an electrically insulating fashion. The battery case houses an electrode group with either its positive or negative electrode plate connected to the electrode rivet. The sealing plate has a periphery region or reinforcement rib which is formed thicker than the rivet region where the electrode rivet attaches, and the outside edges of this reinforcement rib are weld attached to the case.
