Sealed-type battery having a current interrupt device
Abstract:
A sealed-type battery includes an exterior body, a collector terminal, a hollow rivet defining a hollow section, and a reverse plate arranged between the collector terminal and the hollow rivet. The collector terminal includes: a projected section projected; a peripheral edge section provided; and a notch section provided in the peripheral edge section in a manner to surround the projected section and formed in a manner to reduce thickness of the collector terminal. In a projected direction of the projected section, the projected section is thicker than the peripheral edge section. A fitting section, to which the projected section is fitted, is provided in the reverse plate. The sealed-type battery includes a welded section that has a top surface opposing the hollow rivet and that joins the collector terminal and the reverse plate at a position between the projected section and the fitting section.
