PROBLEM TO BE SOLVED: To manufacture an electrode plate for a lead-acid battery with high capacity recovery capability and high quick charge performance by filling a pasty active material in a grid, aging, drying, and forming a non-formed positive plate and a non-formed negative plate at the same time by interposing the suspension between charge and discharge. SOLUTION: A pasty active material comprising lead oxide, dilute sulfuric acid, water, and an additive is filled in a grid made of a lead alloy, aged, and dried. A non-formed electrode plates for a positive electrode and a negative electrode obtained are placed in an electrolyte, and a constant current is applied to the electrode plates to form the electrode plates at the same time. Suspension is interposed between charge and discharge. As suspension, it is preferable to stop discharge until voltage reaches 2.1V/cell after charge across the positive and negative electrode plates formed at the same time is finished. The conversion of lower lead oxide into lead sulfate is retarded, and formation of the electrode plates is uniformly advanced. |
