PURPOSE:To increase cycle life in high rate constant current charge by adding nickel powder and silicic acid anhydride powder to an anode active material. CONSTITUTION:A battery consists of an anode plate in which 0.01-0.2wt.% nickel powder and silicic acid anhydride powder having liquid absorbency, a cathode plate, and a separator. By the interaction of nickel and silicic acid anhydride, the amount of electrolyte around lead sulfate in the anode plate is increased, the accumulation lead sulfate in the anode plate is prevented, and a drop in capacity is retarded. This battery is suitable for quick constant current charge without a decrease in the amount of electrolyte in the plate and separator. |
