  • Patent number: 9666846
    Abstract: A non-aqueous electrolyte secondary battery includes an external electrode terminal, a current collecting tab, a lead, and first and second insulating members. The lead has a hollow portion, electrically connecting the external electrode terminal and the diaphragm. The diaphragm is placed to cover the hollow portion and allow the diaphragm to deform toward the hollow portion. The first insulating member is interposed between the sealing plate and the lead. The second insulating member is interposed between the diaphragm and the current collecting tab. Side walls of the first insulating member and side walls of the second insulating member are coupled to each other. The battery is configured such that the diaphragm deforms toward the outside of the battery when a gas pressure increases in the battery, thereby breaking an electric connection between the external electrode terminal and an electrode assembly of the battery.

  • Patent number: 7781088
    Abstract: 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.

  • Patent number: 7727674
    Abstract: A nonaqueous secondary battery 10 of the invention has an active material compound layer 14 deposed over at least one face of a collector 12 made of metal foil and is equipped with a positive electrode 11 having a portion 13 in a part of which metal is exposed. The positive electrode 11 together with the exposed-metal portion 13 faces a negative electrode 17 through an interposed separator 23, and on that part of the exposed-metal portion 13 that faces the negative electrode 17 through the interposed separator 23 there is formed a protective layer 16 made of a material whose electronic conductivity is lower than that of the metal and which moreover is non-insulative. With such nonaqueous secondary battery 10, should part of an electrode pierce the separator and contact with the other electrode, the battery will be gently discharged, thereby averting abnormal heat generation by the battery and additionally enabling the battery's abnormality to be sensed by the equipment via the fall in battery voltage.
