摘要： A sealed rectangular battery has a conductive battery case including an external casing and a sealing cap. The external casing encloses a generator element and is sealed by attaching the sealing cap using heat. The battery includes an electrode terminal with an opposite polarity to the battery case, and a safety valve. The safety valve includes a cap that is charged with the same polarity as the battery case and a valving element that covers a vent hole. The electrode terminal and safety valve are provided separately at different positions on the battery case. This construction is simpler than conventional batteries where the safety valve is integrally formed with an electrode terminal, which means that the electrode terminal can be miniaturized. This battery also has improved internal resistance.

摘要： A sealed storage battery has a sealing assembly including a hollow rivet mounted to a cover plate via a gasket and a lead piece connecting a positive collector to the hollow rivet. Mounting the hollow rivet to the cover plate is achieved by pressurizing a distal end portion of a hollow shaft of the hollow rivet with a punch having a conical tip end portion so as to caulk the distal end portion of the hollow rivet by enlarging the distal end portion diametrically outward. Tightness between the opposing surfaces of the members among the cover plate, hollow rivet, gasket and lead piece can be enhanced, providing excellent liquid leakage resistance in the battery. A valve body of a safety valve is housed in a positive terminal welded to the head of the hollow rivet.
