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.

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 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.

摘要： By combining crimping fixing and laser welding, a collector attached to a substrate of an electrode assembly is fixed to a terminal. A negative electrode terminal 19A has a terminal portion formed on one side of a flange portion, and a cylindrical crimping member 19b on the other side. The cylindrical crimping member 19b is inserted through openings formed in a first insulating member, a sealing plate, a second insulating member, and a negative electrode collector 18a. The cylindrical crimping member 19b is crimped in a diameter-increasing direction, and is mechanically fixed in a countersunk hole 18c of the negative electrode collector 18a. A peripheral portion of a thin-walled portion 19d having a thickness smaller than those of other portions formed at the tip end portion of the cylindrical crimping member 19b is thoroughly adhered and welded by a high energy beam to the edge of the countersunk hole 18c.

摘要： A prismatic secondary battery is provided with a negative/positive electrode collector (18), which are disposed on either one of a wound negative/positive electrode substrate exposed portion (15), and a negative/positive electrode collector receiving member (19) which is disposed on another surface. At least one of the negative/positive electrode collector has a recess portion (30) formed in part on a surface on the side not facing the negative/positive electrode substrate exposed portions so as to be thinner than the thickness of the other portion. Resistance welding is carried out in this recessed part, thereby a large welding nugget is formed between the negative/positive electrode exposed portion and the negative/positive electrode collector.

摘要： A method for producing a secondary cell having a flat wound electrode body that inhibits the bending of the electrode board caused by charging and discharging and inhibits resulting swelling of the cell and deterioration of cycle characteristics is provided. The method has the steps of: winding, with a winding core, a positive electrode board, a negative electrode board, and a separator provided between the positive and negative electrode boards, and fixing the winding end, thereby preparing an approximately cylindrical electrode body; after the step of preparing the electrode body, deforming the electrode body into a shape with an approximately oval cross section by pressing the approximately cylindrical electrode body from a direction perpendicular to the winding axis, and rotating the deformed electrode body in the winding direction, thereby relaxing the winding state; and after the relaxation steps, pressing the electrode body into the flat wound electrode body.
