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.

In a prismatic sealed secondary battery provided with an outer can made of a metal, the ability of inserting the electrode assembly into the outer can is improved to restrain the displacement and damages of the insulation member when inserting the electrode assembly into the outer can. The prismatic sealed secondary battery of the present invention includes an insulation member having a bottomed box shape which is a shape obtained by eliminating the upper surface from the surfaces of a hexahedron having a cuboid form, wherein each width of at least a pair of side surfaces facing each other in the insulation member is smaller than the width of the electrode assembly facing the pair of side surfaces.

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.

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.

A sealing plate for a prismatic secondary battery includes a pair of mouths for attaching a negative and positive electrode terminals, one mouth being formed near one end in a longitudinal direction of the sealing plate, and the other mouth being formed near the other end, coining areas used for positioning of an insulating member and formed around the pair of mouths on a front face of the sealing plate, a gas release valve and an electrolyte pour hole formed between the pair of mouths, and grooves formed between the respective coining areas and the long side edge of the sealing plate. The groove has a smaller depth near the gas release valve than the depth near the coining area. Even when the sealing plate is produced through forging, the front face has good flatness and the coining areas are unlikely to have a sink mark or a shear drop.

A prismatic nonaqueous electrolyte secondary battery includes a convex portion on a stepped portion of a stepped through hole of a positive electrode external conduction member. An upper end side of a caulked portion of a positive electrode terminal member is caulked by being inserted from a side of a small-diameter portion into the stepped through hole of a positive electrode external conduction member, and a convex portion of the positive electrode external conduction member is covered with a tip side of the caulked portion. Therefore, a terminal member and an external conduction member have a great bond strength, and rarely rotate with respect to each other. Thus, there is less concern that a conductivity decreases even when the battery is used under an environment including a lot of vibrations.
