A comparative study of lead alloy electrode and CF/aamp;beta;-PbO2 electrode for zinc electrowinning was discussed. The effect of electrodeposition time on the preparation and properties of the CF/β-PbO2 electrode was firstly studied. Surface morphology, interface properties, electrochemical property and corrosion resistance of the CF/β-PbO2 electrodes were investigated. It was found that the optimal conditions are 40 mA•cm-2, 150 g/L Pb(NO3)2 and 100 min. Under this conditions, a smooothest surface of β-PbO2 active layer is obtained. The weightlessness rate is 0.22%. The interface resistivity of the electrode is 6.79×10-5 Ω•m. The oxygen evolution overpotentials of the electrode is 0.931 V. Compared to the traditional lead alloy electrode, the self-corrosion potential of the CF/β-PbO2 electrode is 1.085V.
