Reference numeral 4 is a battery case made of a synthetic resin film. (Hereinafter, referred to as "conventional product 2") Problems to be solved by the invention As compared with the conventional product 2 and the conventional product 1, the amount of retained electrolyte increases,
Since the diffusion of the electrolyte is also good, the capacity is considerably high. However, when discharging, the entire active material is effectively used, but during charging, the active material on the outer surface of the electrode plate does not easily react,
Furthermore, there is a drawback that the life is shortened by converting to lead sulfate.
