摘要
采用化学氧化方法在水相介质中合成了部分邻位连有 - S- S-结构的聚苯胺类电极材料 ,结合SEM、IR、粒度测试以及充放电技术对所合成材料的微观形貌、官能团结构、粒径分布以及电化学性能进行了研究。实验结果表明 ,文中介绍的部分具有 - S- S-结构的苯胺聚合物在作为正极材料与锂对电极组成电池后 ,具有 1 86 m A.h/ g的首次放电容量和较好的循环性能 。
The aniline polymer where the -S-S- structure were linked in the neighbouring site of aniline was synthesized by chemical oxidation method, with SEM, IR, granularity and charge discharge technology the synthesized polymer′s microstructure, function group, granular distribution and electrochemical properties were studied. The experimental results illustrate that:when this polymer is used as positive electrode in lithium battery, a first discharge capacity of 186 mA·h/g and good circle property can be found, therefore, it is a promising positive electrode for Lithium secondary battery.
