Abstract
PbO<sub>2</sub> electrodes exhibit symmetry on the CV curve in MnSO<sub>4</sub> bath (oxidation peak occurs at 1.00–1.40 V) and asymmetry in Mn(NO<sub>3</sub>)<sub>2</sub> plating solution (negative current value at 1.00–1.18 V). The current rapidly rises to a large peak current at 1.25 V.
