Abstract

Low‐rate (∼ 0.5 mV/sec) cathodic linear sweep voltammetry (LSV) experiments were conducted on preanodized antimonial and nonantimonial lead. The sweeps were supplemented by current‐time traces obtained during the short term (≤ 1 hr) anodic treatment above the reversible potential in electrolytes. Despite complications from additional substrate corrosion during the sweeps, semiquantitative observations were possible and the cathodic discharge could be resolved into components. A major finding was that antimony in the lead retards the formation of in the preliminary anodic treatment. Implications from the results with regard to the behavior of the Pb‐acid battery positive plate are briefly discussed.
