    Abstract: 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.

    Abstract: A nonaqueous electrolyte secondary battery includes a positive electrode plate including a positive electrode core and a positive electrode mixture layer formed thereon; a negative electrode plate including a negative electrode core and a negative electrode mixture layer formed thereon; a wound electrode assembly in which the positive electrode plate and the negative electrode plate are wound with a separator therebetween so as to be insulated from each other; a nonaqueous electrolyte solution; a pressure-responsive current interruption mechanism electrically connected to at least one of the positive electrode plate and the negative electrode plate; and an outer casing. Excess electrolyte solution is present outside the electrode assembly in the outer casing. The liquid level of the excess electrolyte solution is at such a height that the excess electrolyte solution does not come into contact with a component of the current interruption mechanism when the outer casing is placed horizontally.

    Abstract: A highly reliable prismatic secondary battery with a current interruption mechanism that is unlikely to be damaged even if the battery is subjected to shock due to vibration, falling, etc. A second insulating member that has a through-hole is disposed between an inversion plate and the first region of a positive electrode collector, and through the through-hole the first region of the positive electrode collector is electrically connected to the inversion plat. First to third projections to formed around the through-hole formed in the second insulating member fit respectively into first to third openings formed in the first region of the positive electrode collector, and the diameters of their apexes are widened, thus forming first to third fixing portions. Thereby, the second insulating member is robustly joined to the first region of the positive electrode collector.

    Abstract: A current interruption mechanism for prismatic secondary battery includes a tubular conductive member electrically connected to a positive electrode external terminal, an inversion plate, and a positive electrode collector connected to the inversion plate. The positive electrode collector has a first region that is parallel to a sealing body and a second region that is connected to a positive electrode plate. The boundaries between the first and second regions are disposed further outward than the inner surface of the tubular conductive member, and at least one of the edge portions, other than the boundaries between the first region and second region, is located further outward than the inner surface of the tubular portion of the conductive member. The current interruption mechanism is unlikely to be damaged even if the battery is subjected to shock due to vibration, falling, etc.
