  • Patent number: 8986874
    Abstract: 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.
