Document Type and Number:
WIPO Patent Application WO/2006/057083
Kind Code:
A1
Abstract:
[PROBLEMS] To regenerate a used lead battery which could not be regenerated conventionally, or increase the capacity of a new lead battery. [MEANS FOR SOLVING PROBLEMS] A used lead battery is regenerated or the capacity of a new lead battery is increased by injecting electrolyte containing 39-60% of pure water, 5-15% of sulfuric acid compound, and 20-30% of colloidal silica into a lead battery from which diluted sulfuric acid electrolyte has been removed, dissociating sulfation by being ionized from the positive electrode and the negative electrode of the lead battery injected with electrolyte by applying a DC pulse of 12000-35000 Hz to between the positive electrode and the negative electrode, and charging the lead battery by applying a DC voltage to between the positive electrode and the negative electrode simultaneously with or after application of the DC pulse.
