    摘要: The positive electrode substrate exposed portions or the negative electrode substrate exposed portions, or both, of an electrode assembly is split into two groups, and therebetween is disposed an intermediate member made of a resin material and holding one or more connecting conductive members. Collector members for the substrate exposed portions split into two groups is electrically joined by a resistance welding method to the substrate exposed portions split into two groups, together with the connecting conductive member(s) of the intermediate member. The resin material portion of the intermediate member protrudes, in the extension direction of the substrate exposed portions split into two groups, beyond the ends of the substrate exposed portions split into two groups and the ends of the collector member to a prismatic outer can. This structure enables enhanced resistance between the substrate exposed portions and the collector member and curbs variation in the welding strength.

    摘要: A non-aqueous electrolyte secondary battery has a current interrupting mechanism with excellent impact and vibration resistance. The mechanism includes a fragile portion which breaks when the diaphragm deforms and rises upward, thereby interrupting current flow thereto; and an insulating current collecting tab holder into which a part of a current collecting tab is inserted. The tab holder has a tab receiving portion into which the insert member of the tab is inserted. The tab receiving portion is provided on the inner and outer surfaces thereof with a holder hole, which overlaps with a throughhole when the insert member is inserted. The diaphragm is disposed outside the tab receiving portion so as to cover the holder hole and electrically connected at its center bottom to the fragile portion via the holder hole. The gas pressure in the battery acts on the fragile portion and the inner side of the diaphragm.

    摘要: The method for manufacturing a sealed battery of the invention includes an ultrasonic fusion process whereby layers of a positive electrode substrate exposed portion 11 are ultrasonically fused to form a positive electrode fused portion 11a at the positive electrode substrate exposed portion 11, and layers of a negative electrode substrate exposed portion 12 are ultrasonically fused to form a negative electrode fused portion 12a at the negative electrode substrate exposed portion 12; and an electrode body formation process whereby a high-energy beam is directed at the positive electrode fused portion 11a to weld a positive electrode collector to the positive electrode fused portion 11a, and a high-energy beam is directed at the negative electrode fused portion 12a to weld a negative electrode collector to the negative electrode fused portion 12a, thus forming an electrode body in which a positive electrode collector is welded to one end of the electrode group and a negative electrode collector is welded to the other end. Thereby, the required weld strength is obtained despite a reduction in the energy for welding, and a sealed battery is obtained which has low internal resistance and in which internal short-circuiting is prevented.
