Abstract: The anodic oxygen behavior of new lead-calcium alloys with different lanthanum content were investigated in 1.28g.cm-3 sulfuric acid solution by means of linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS). The experimental results showed that the oxygen overpotential and the resistance of oxygen reaction on the electrodes of lead-calcium alloys with lanthanum are higher than that on the Pb electrode, It was found that the addition of La can inhibit the oxygen evolution reaction on the lead-calcium alloys electrodes, and La amounts of 0.005 wt.% in lead-calcium alloys electrodes can lead to a more effective inhibition.
