Abstract: A nonaqueous electrolyte secondary battery includes an electrode body and an electrolytic solution in an outer can and a cathode external terminal on the open-end side of the outer can. The battery further includes a current cutoff mechanism (CID). The CID is located on the electrical conduction pathway between the cathode external terminal and the electrode body and interrupts the electrical coupling therebetween in response to an increased internal pressure in the battery. The CID includes a seal lead, a diaphragm, and a dielectric film. The seal lead has a cylindrical opening on the electrode body side. The diaphragm tightly closes the cylindrical opening and, in response to the increased internal pressure in the battery, deforms to interrupt the electrical coupling between the electrode body and the seal lead. The dielectric film is on the electrode body side of the diaphragm.

Abstract: A nonaqueous electrolyte secondary battery includes a conductive outer can, an electrode body in the outer can, a conductive seal plate tightly closing an open end of the outer can, and a cathode external terminal on the seal plate. The battery further includes a current cutoff mechanism (CID). The CID is located on the electrical conduction pathway between the cathode external terminal and the electrode body and interrupts the electrical coupling therebetween in response to an increased internal pressure in the battery. The CID includes a thin portion of the seal plate and a diaphragm. The diaphragm deforms to interrupt the electrical coupling between the cathode external terminal and the electrode body in response to the increase in the internal pressure in the battery. A cathode collector lead electrically couples the electrode body and the seal plate, and the seal plate connects the diaphragm and the cathode collector lead.
