【摘要】 采用线性扫描（LSV）、交流阻抗（EIS）、循环伏安（CV）、金相实验等方法对比Pb-Ca-Sn-Al合金中添加稀土元素对合金高温条件下电化学性能的影响。实验结果表明,在合金元素中添加稀土在高温下能抑制氢气和氧气的析出,并能够促使合金表面生成更多的PbO和PbO₂氧化膜,这有利于铅酸蓄电池免维护性能的提高以及提升板栅的充放电性能。更多还原

【Abstract】 Linear potential scanning method（LSV）, electrochemical impedance spectroscopy（EIS）, cyclic voltammetry（CV）,metallographic experiment and other analytical methods were used to investigate the electrochemical performance of Pb-Ca-Sn-Al-Re alloy at high temperature compared to Pb-Ca-Sn-Al. The experimental results indicate that the addition of Re can inhibit the oxygen and hydrogen evolution reaction and greatly increase the generation of PbO and PbO₂. It can improve maintenance-free performance of lead acid battery and enhance charge-discharge performance of grid alloys.更多还原
