英文摘要	用循环伏安法研究了ＰｂＣＯ３粉末微电极转化为ＰｂＳＯ４电极的活化方法和条件．发现在２～２－５ｍｏｌ／ＬＨ２ＳＯ４溶液中由ＰｂＣＯ３转化成ＰｂＯ２／ＰｂＳＯ４和ＰｂＳＯ４／Ｐｂ电极时，以不对称交变讯号活化（化成）后，其循环伏安性能与由球磨机生产的ＰｂＯ粉所制得的相应电极性能相近．对于负极，在含有乙炔黑胶体的Ｈ２ＳＯ４溶液中化成，由于碳胶粒在ＰｂＳＯ４晶体上的吸附，阻止了充放电过程中电极材料的收缩，同时增加了电极的导电性，从而促进活性物质的转化形成; Lead carbonate which was an intermediate product in lead hydrometallurgy without pollution of lead vapor and sulfur dioxide was selected as electrode material of lead_acid batteries. In the present work,the performances of PbO 2/PbSO 4 or PbSO 4/Pb electrode transformed from PbCO 3 have been investigated by powder microelectrode technique combined with cyclic voltammetry.The results show that the CV characteristics of either negative or positive electrode prepared from PbCO 3 is as good as that of both electrodes made from lead oxide produced by mill machine,when a powder microelectrode with PbCO 3 transformed into PbSO 4 in 1.0 mol/L H 2SO 4 solution,and then activated to form Pb or PbO 2 using an unsymmetrical interchangeable signal( Q a/ Q c or Q c/ Q a being 0.2～0.4) in 2.0～2.5 mol/L H 2SO 4 solution.Furthermore,comparing the negative electrode activated in 2.5 mol/L H 2SO 4 solution containing 4% carbon colloid with one activated in the same H 2SO 4 solution concentration without ABC,the cyclic voltammetric characteristics of the former has been obviously improved.It is possible that the carbon colloid particles can be adsorbed on PbSO 4 crystals,which could increase the conductivity and reduce the shrinking of the electrode; 作者联系地址：武汉大学化学与环境科学学院!武汉430072,武汉大学化学与环境科学学院!武汉430072,武汉大学化学与环境科学学院!武汉430072,武汉大学化学与环境科学学院!武汉430072,武汉大学化学与环境科学学院!武汉430072; Author's Address: Dept.of Chem.,Wuhan Univ.,Wuhan 430072
