1. ELECTROCHEMICAL BEHAVIOR

Electrochemical processes form the foundation for how lead plates store energy. The electrochemical cell operates through redox (reduction-oxidation) reactions occurring at the electrodes. In a lead-acid battery, lead dioxide (PbO2) serves as the positive electrode, while spongy lead (Pb) functions as the negative electrode. When the battery discharges, lead dioxide undergoes reduction, gaining electrons, while spongy lead loses electrons through oxidation. The electrolyte, usually sulfuric acid (H2SO4), facilitates ions transferring between the electrodes, contributing to the overall efficiency of energy storage.

During charging, the reverse process occurs. The oxidation of lead produces lead sulfate (PbSO4), while lead dioxide is regenerated at the positive electrode. This cyclical process underscores the battery’s ability to repeatedly store and release energy. The efficiency of these electrochemical reactions is heavily influenced by several factors—including electrolyte concentration, temperature, and the surface area of the electrodes—which all determine the battery’s performance attributes.
