Lead-Acid Battery Charging: What Reaction Occurs and How It

Primary reactions during charging of a lead-acid battery involve converting lead sulfate back into lead and lead dioxide. The half-reaction at the positive plate converts lead sulfate (PbSO4) into lead dioxide (PbO2) while releasing sulfuric acid (H2SO4) into the electrolyte. The negative plate undergoes a similar conversion, turning lead sulfate into sponge lead (Pb). This
