PURPOSE:To decrease the internal resistance of a battery and to increase the amount of an electrolyte to increase discharge performance by interposing a retainer between two electrodes having the same polarity, and separating positive and negative plates with a thin separator. CONSTITUTION:Electrolyte retainers 2 are interposed between two positive plates 4, 4' and between two negative plates 5, 5'. The retainer 2 is made of a highly porous material which is acid resistance and oxidation resistance and from which substances farmful to a battery are not dissolved. A thin separator with low resistance is interposed between the positive plate 4 and the negative plate 5 to separate them. This electrode group is inserted into a container 7 by applying pressure, and a vent plug 8 is installed to form a lead-acid battery. The internal resistance of the battery is decreased and the amount ot the electrolyte is increased without widening the distance between plates to increase discharge performance. |
