Abstract
A stable and durable electrode assembly for a lead-acid storage battery to provide a longer-life lead-acid storage battery is described. A synthetic resin-made separator and a glass mat, which is wider than the separator, are coordinately stacked together and then folded in such a manner that the separator is positioned within the glass mat and the side edge portions of the separator overlap and the side edge portions of the glass mat overlap. The overlapped side edge portions are respectively seal-bonded to each other to provide a pocket-type electrode assembly wherein the outer surface thereof is a pocket-type glass mat which surrounds a pocket-type separator.
