摘要: A secondary battery comprises a single-plate lead acid (Va), positive electrode capacitor layer and negative layer, which are formed on the respective surfaces of plate, plate. Each plate contains an active material, to have configuration in activated carbon has concentration gradient. The electronic resistance between collector terminal center portion where is present at high lower than low concentration. In battery, charges accumulated layer.
