PURPOSE:To enhance the charge/discharge characteristic at low rate of current and reduce the weight of battery by arranging a lead foil or lead plate on one side or both sides of a group of electrode plates, consisting of a pos. elect. plate, neg. elect. plate, and separator, with separator interposed. CONSTITUTION:With separator 3 interposed, a lead foil or lead plate 4 is arranged on one side or both sides of a group of electrode plates consisting of a pos. elect. plate 1, a neg. elect. plate 2, and a separator 3 interposed therebetween, and the end of this lead foil or plate 4 is connected with the neg. elect. plate 2, and further paradium ion is added to the electrolytic solution. This allows dispersed flow of current in the lead foil or plate 4 in case charge is made in the overcharge region, and the current flowing through the neg. elect. plate 2 recreases relatively to decrease the amount of lead sulfate accumulated on the neg. elect. plate 2, which enhances the overcharge characteristic, and the catalyst action of paradium ions added to the electrolytic solution generates large flow of current and minimizes deterioration of the neg. elect. plate 2 even through the area of the lead foil or plate 4 is set small, and thus the weight of battery is reduced. |
