The separating member is sealed off from the inner wall of the pressure equalization chamber, wherein the fluid connection with the battery chamber opens in a first chamber region of the pressure equalization chamber which is separated by the separating member from a second chamber region. The separating member permits a volume change in one of the chamber regions given a corresponding volume change in the other chamber region. The second chamber region is in fluid communication with the outside of the battery chamber via a venting path.

    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.
