The Lead–Acid Battery: Its Voltage in Theory and in Practice

The cathode consists of lead(IV) oxide deposited on a lead plate. During discharge the red-brown oxide is reduced to lead(II) sulfate by the reaction PbO 2 (s) + 2H+(aq) + H 2 SO 4 (aq) + 2e → PbSO 4 (s) + 2H 2 O( ) The cathode has a positive charge because electrons are con-sumed there. The two half-reactions can be combined to give the overall discharge reaction Pb(s) + PbO 2 (s) + 2H 2 SO
