摘　　要：用反相微乳聚合法制备了十二苯磺酸(DBSA)掺杂的导电聚吡咯纳米材料,DBSA既作为表面活性剂又作为掺杂剂,能够提高聚吡咯的导电性.用制备出的DBSA-PPy为正极材料,石墨为负极材料组装双离子电池,测试结果表明,C/DBSA-PPy电池的电化学性能已达到传统锂离子电池的水平,这是因其具有较高的导电性和特殊掺杂结构的聚吡咯使其电化学性能得到优化.Conducting DBSA-PPy was fabricated by reverse microemulsion polymerization. DBSA increase the conductivity of PPy when it is used as the dopant and was surfactant, since the W/O microemusion can supply nano-reactor. The electrochemical performance of dual ion battery with graphite as the anode and DBSA-PPy as the cathode materials was tested, the result shows that the battery has as good electrochemical characteristics as traditional lithium-ion battery., due to the high conductivity and doped structure of the prepared DBSA-PPy, which indicates that conducting polymer as positive materials of electrode is hopeful for the application.
