Study on CV behavior of electrodeposited lead alloy in sulfuric acid

To study the electrochemical performances of lead foam electrode prepared from electrodeposited lead-tin alloy on copper foam substrate and cast lead alloy electrode, cyclic voltammogram (CV) method was used. After several cycles, the CV curves and surface morphology of two electrodes were compared. Results show that in sulfuric acid the main electrochemical reactions on electrodeposited lead-tin alloy are about the same as that on cast lead alloy, and after several cycles the electrodeposited lead-tin alloy electrode possesses more uniform surface morphology and structure.
