Abstract
The impedances of reduced layers of PbO2 in sulphuric acid are measured at potentials in the range between initial discharge and complete reduction to lead. The electrode behaviour is fairly polarizable when the electrode is remote from the PbSO4/Pb potential. Near the reversible potential the electrode behaves as a porous electrode under charge-transfer and diffusion control.
