Abstract In order to explore the electrochemical performance of Pb(1%Ag)/Al layered composite anode, linear scanning voltammetry (LSV), anode surface potential distribution test method and scanning electron microscope (SEM) were used to analyze the polarization curve, potential distribution curve and corrosion morphology of the Pb(1%Ag)/Al layered composite anode and the conventional Pb-1%Ag alloy anode. The results showed that the passivation potential of the Pb(1%Ag)/Al layered composite electrode was 31.1% lower than that of the conventional Pb-1%Ag alloy electrode, and the potential distribution was more uniform than that of the conventional Pb-1%Ag alloy electrode, the corrosion morphology was denser than that of the conventional Pb-1%Ag alloy electrode. Therefore, Pb(1%Ag)/Al layered composite electrode exhibited lower electrode potential, uniform potential distribution and higher corrosion resistance compare to the conventional Pb-1%Ag alloy electrode. At the same time, ANSYS was used to simulate the electric field distribution of parallel plate capacitors,for simulating the potential distribution, combined with the potential distribution curve, the potential distribution trend was analyzed to verify the accuracy of the potential distribution test method. The results showed that the simulated data was consistent with the experimental data, which further confirms that the Pb(1%Ag)/Al layered composite anode has high electrical conductivity and electrochemical performance.
