Abstract
Positive and negative electrode plates are alternately stacked upon one another with intervening separators to constitute an electrode plate group . The respective electrode plates are laterally offset so that side edges of the electrode plates protrude on the opposite sides. Collector plates are perpendicularly welded to the side edges of the electrode plates on both sides of the electrode plate group . Loose ends of the outermost negative electrode plates that are not welded to the collector plate are secured to the electrode plate group by a holding tape
