<P>PROBLEM TO BE SOLVED: To regenerate a used lead battery that can not be regenerated conventionally or to increase the capacity of a new lead battery. <P>SOLUTION: A used lead battery is regenerated or the capacity of a new lead battery is increased by injecting an electrolyte containing 39-60% of pure water, 5-15% of a sulfuric acid compound, and 20-30% of colloidal silica into a lead battery from which a diluted sulfuric acid electrolyte is removed, dissociating sulfation by being ionized from the positive electrode and the negative electrode by applying a DC pulse of 12,000-35,000 Hz between the positive electrode and the negative electrode of the lead battery injected with the electrolyte, and charging the lead battery by applying a DC voltage between the positive electrode and the negative electrode simultaneously with or after application of the DC pulse. <P>COPYRIGHT: (C)2008,JPO&INPIT |
