摘要
应用交流阻抗,交流伏安和循环伏安等方法研究了Pb-Ca-Sn-Re合金和Pb-Ca-Sn合金在1.28 V(vs.SCE)和4.5 mol/L硫酸溶液中的阳极行为.结果表明:稀土铅钙合金提高了合金的耐腐蚀性能,同时抑制其阳极膜中Pb(Ⅱ)化合物的生长,从而降低阳极膜的阻抗,提高膜的导电性能,这对改善电池的深循环性能十分有利.
The anodic behaviors of Pb-Ca-Sn-Re and Pb-Ca-Sn alloys were investigated at 1.28 V （vsHg/ H2SO4 ） in 4.5 mol/L sulfuric acid solution by means of ac voltammetry, ac impedance and cyclic voltammetry. The results showed that the corrosion-resistance property of Pb-Ca-Sn-Re alloy is better than that of tradditional Pb-Ca-Sn alloy, the growth of Pb（ Ⅱ ） compounds was inhibited in the film of Pb-Ca-Sn-Re alloy, and the film impedance of Pb-Ca-Sn-Re alloy was decreased, indicating that the conductivity of the film was increased, which is helpful to enhance the deep recycling property for lead acid battery.
