摘要： 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.

摘要： A crimped portion of a positive electrode external terminal is crimped on its upper end side to be electrically connected to a positive electrode terminal plate. This crimped portion is welded to the positive electrode terminal plate by applying high energy beams. The negative electrode side has a configuration similar to that of the positive electrode side. The contact area between the positive electrode terminal plate and the crimped portion of the positive electrode external terminal is set smaller than the corresponding contact area on the negative electrode side, and the volume of the crimped portion of the positive electrode external terminal is set larger than that of the corresponding crimped portion on the negative electrode side. Thus, a prismatic secondary battery is provided that shows strong joining strength between the external terminal and the terminal plate, suppressed internal resistance variations, and improved reliability.

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 secondary battery includes an electrode body, an outer can, a sealing plate, electrode terminals, and a current interrupt device. The electrode terminals includes a first electrode terminal and a second electrode terminal, and are electrically connected to the electrode body through a collector member. The current interrupt device includes a short-circuit part that short-circuits the battery when the internal pressure exceeds a set pressure, and a fuse part disposed in the collector member. The fuse part is disposed close to an upper end corner portion serving as a boundary portion between an upper surface and a side surface of the secondary battery. A binding member includes a protective cover portion that covers the upper end corner portion of the secondary battery, and the protective cover portion includes an upper-surface covering part and a side-surface covering part.

摘要： A prismatic secondary battery includes a prismatic hollow outer body having a mouth and a bottom; a flat electrode assembly, a positive electrode collector, a negative electrode collector, and an electrolyte, all of which are stored in the prismatic outer body; a sealing plate sealing up the mouth of the prismatic outer body; and a positive electrode terminal attached to the sealing plate in an electrically insulated manner. The sealing plate includes a gas release valve and an electrolyte pour hole and further includes, on the front face, a concaved flat face having an identification code. With the prismatic secondary battery of the invention, a jig for assembly or the like is unlikely to come into contact with the identification code during an assembly process of the prismatic secondary battery, hence the identification code is unlikely to be abraded, and the traceability is unlikely to be lost.
