A Study on the Property Improvement of a Lead-Acid Battery by Inhibitor Addition

Lead-acid battery is being most widely used with secondary battery because of its low price, and long life cycles. But According to using for a long time, its voltage, capacity, and recovery ability is decreased gradually. Therefore there are many papers about improving the property of a lead-acid battery. One of them is to slow down sulfation due to formation of inner PbSO sub(4) by adding inhibitor to electrolyte, however it was not well known what is inhibitor's composition and its role acting on both cathodic and anodic electrode because of its know-how of every country and companies. The purpose of this paper is to study about improvement of property of lead-acid battery by adding one of the inhibitor to H sub(2) SO sub(4) electrolyte.
