(JP11167914-A)   NOVELTY - The current collector (7) is formed from a rectangular flat plate (7a) with an I-shaped cutout hole (7b) passing the plate center, ending proximate the outer peripheral edge parts (7d). A rib-formed projection (7e) of the I-shaped cutout crosses the electrode plate coiling start terminal part of the electrode plate assembly and so can secure welding spots over a wide region in the diameter direction of the electrode plate assembly.    USE - For spirally wound cylindrical storage batteries.    ADVANTAGE - The storage battery permits charge and discharge at high rate through the current collector.
