Abstract

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.
