摘　　要：采用化学法用苯胺与盐酸和 L-胱氨酸掺杂合成聚苯胺 ,将样品与一定量的导电物质石墨混合 ,制备成电极材料测定其电极过程的循环伏安特性 ,详细研究了各种因素对其充放电性能的影响。经电化学性能测试 ,发现其氧化还原可逆性和稳定性都较好。电极样品在 1 0 m A/ cm2充电 2 h,以 2 m A/ cm2恒电流、终止电压为 1 .0 V的放电制度下 ,可持续放电 8h。结果表明 ,本法所制备的聚苯胺掺杂复合电极材料 ,充放电效率较高 ,放电容量大 。Polyaniline was prepared by chemical method, doped by HCl and L cystine. The mixed electrode with polyaniline and graphite was prepared, and its cyclic voltammetry property, charge property and discharge property were studied. The test condition is that the charge current is 10 mA/cm 2, the charge time is 2 h, the discharge current is 2 mA/cm 2 and the terminative voltage is 1.0 V. The result indicates that the electrode has high efficient of charge and stable structure, and it is a kind of new polymer material which is worthy of studing deeply .
