摘要： A wound electrode body is fabricated by laminating and winding positive and negative electrode sheets together with a separator therebetween for insulation. On both positive and negative electrode side ends of the wound electrode body, laminates of current-collecting foil layered portions of the electrode sheets are bent or folded f toward the outer peripheral side to be separated into two. The separated laminates and forked connector leaves are overlapped and clamped between an ultrasonic chip and an anvil. Then, they are welded. The forked connector leaves are arranged such that no opposing forked connector leaf is present in the direction of a line normal to the forked connector leaf, so that the anvil does not have to be cantilevered. This allows welding by using the ultrasonic chip and the anvil without interfering with the collector rs. As a result, the quality of welding is improved.

摘要： A prismatic secondary battery includes a battery case in a prismatic shape and a battery cover which seals up an opening part of the battery case. The battery cover has a convex part which projects toward the inside of the battery case, faces an inner surface of a side wall part of the battery case, and extends continuously along the entire periphery of the side wall part. Cover thickness of a contact part of the battery cover which is in contact with the upper end of the side wall part of the battery case at a position outside the convex part is greater than ½ of cover thickness of a blockage part blocking up an opening part at a position inside the convex part and is less than the cover thickness of the blockage part.

摘要： A rechargeable battery includes a battery pack, a battery lid, and an electrode and an external terminal connected by an electricity connector. A laminated portion of the electrodes comprising a lump of wound electrodes is separated into two bundle electrode connecting portions from a center side of the wound electrodes in the thickness direction outward of the battery pack. The electricity collector is provided with a main plate joined to the bundles, a rib plate bent from the main plate and extending outward of the battery pack, a mounting plate extending along the inside of the battery lid, and a connecting plate bent from of the mounting plate and extending toward a bottom surface of the battery pack. A coupling plate is inclined from this bottom end of the connecting plate toward the bundles and is coupled to one end of a joint plate on the battery lid side.
