【摘要】 利用循环伏安线性扫描,研究了Pb-Ca-Sn-Al-Bi和Pb-Ca-Sn-Al合金电极分别在硫酸/磷酸中的阳极氧化行为。分析了Bi(Ⅲ)的掺入对铅酸蓄电池电化学性能的影响。结果表明:Pb电极中掺入Bi(Ⅲ)能提高其稳定的放电容量;另一方面,Pb电极在磷酸胶体电解液中的电量表现出明显增大的趋势,而在磷酸溶液中的电量增大相对不明显。更多还原

【Abstract】 The anodic oxidation behavior of Pb-Ca-Sn-Al-Bi and Pb-Ca-Sn-Al alloy electrodes in sulfuric acid/phosphorous acid electrolytes was studied by linear scan cycling voltammetry.The influence of Bi(Ⅲ) doped on the electrochemical performance of lead acid battery was analyzed.The results showed that Bi(Ⅲ) doped could increase the steady discharge capacity of the lead electrode.On the other hand,the electrochemical capacity of Pb electrode in phosphorous acid gel electrolyte increased apparently,while that in phosphorous acid increased little.更多还原
