PROBLEM TO BE SOLVED: To prevent damage on collecting tabs at an assembly process for a secondary battery capable of taking out power generated of a wound-up electrode body 2 inside a battery can 1 from an electrode terminal mechanism 90 through a plurality of the collecting tabs. SOLUTION: A plurality of the connecting tabs 3 are taken out of the wound-up electrode body 2. The electrode terminal mechanism 90 is provided with an electrode terminal 91 penetrating the battery can 1, and a flange part 92 is formed at a base end part of the electrode terminal 91, and at the same time, a screw shaft piece 96 is set in protrusion at the flange part 92 to which a nut is screwed. Between the flange part 92 and the nut 97, tip parts 31 of the plurality of the collecting tabs 3 are pinched in a state superimposed with each other. Also, an aluminum foil 4 is interposed between the tip parts 31 of the superimposed collecting tabs 3 and the nut 97. COPYRIGHT: (C)2003,JPO |
