摘　　要：影响铅酸蓄电池深循环的关键在于板栅界面腐蚀膜的导电性。通过循环伏安和交流阻抗等测试,考察了在铅钙合金和铅锑合金中添加金属铈和钇对合金性能的影响。结果表明:金属铈和钇能提高铅钙合金和铅锑合金的析氢、析氧过电位和合金的耐蚀性能,并且可以抑制放电时腐蚀膜中PbO2的还原及非化学计量PbOn的生成,使腐蚀膜更具导电性,提高板栅合金的深循环性能。The conductivity of grid interface corruption film determines the deepcycle performance of leadacid battery. The effect of additional Ce and Y in PbCa and PdSb alloy were studied by means of cycle voltammetry and AC impedance. The results show that Ce and Y can improve the overpotential of hydrogen and oxygen evolution on PbCa and PdSb alloy and can restrain the reduction of PbO2 in the corrosion film and the formation of nostoichiometric PbOn during discharge. Furthermore, they can improve the conductivity of the corrosion film and increase the deepcycle performance of grid alloy.
