摘　　要：用循环伏安、线性扫描伏安和交流阻抗法研究了Pb和Pb-Ca-Sn-Al电极在含与不含Sn2+的硫酸中的电化学性能。添加Sn2+,提高了Pb和Pb-Ca-Sn-Al电极在硫酸中的抗腐蚀性和导电性能,Pb(Ⅱ)碱性化合物还原峰的电流分别减小至约1/10和1/5。The electrochemical performance of Pb and Pb-Ca-Sn-Al electrodes in sulfuric acid with or without Sn^2＋ was studied by cyclic voltammetry,linear sweep voltammetry and electrochemical impedance spectroscopy methods.The addition of Sn^2＋ improved the anti-corrosion performance and conductivity of Pb and Pb-Ca-Sn-Al electrodes,the reduction peak currents of Pb（Ⅱ） basic compounds decreased to 1/10 and 1/5,respectively.
