摘　　要：采用微乳液法合成不同物质的量比的十二烷基苯磺酸(DBSA)与磷酸(H3PO4)共掺杂的聚苯胺(PAn),红外光谱(FI-IR)分析表明,聚苯胺骨架键型为醌环、苯环、QBQ、C-N、C-H、N-H、S=O及-SO3,结构齐全;通过扫描电子显微镜观察表明,聚苯胺形态为条片状,厚度约为100nm;电导率测试结果为,当掺杂体系中n(DBSA)∶n(H3PO4)=1∶4时,产率可以达到115%,PAn样品的电导率高达2.17S/cm。以其制作的电极进行循环,0.1C充放机制,首次容量59.4mAh/g,前20次附加循环容量保持在38mAh/g以上。Co-doped polyanilines were synthesized with different mol rations of DBSA and H3PO4 using micro-method.FT-IR analysis results showed that the types of chemical bonds are C-H、N-H、 S=O and-SO3,belong to those of polyanliline.The polyaniline＇s shapes were bends or pieces with 100 nm thickness.The biggest conductivity was 2.17 S/cm when n（DBSA）∶n（H3PO4）=1∶4.polyaniline electrode＇s first discharge capacity was 59.4 mAh/g at 0.1C,when the attached cycle period reached 20,the capacity remained at about 38 mAh/g.It was pointed out that the stability model of ballistic and plastic deformation recovering force ability（H） could be set to determine the sturdiness of extraction-insertion of Li＋ in positive/negative material.When H of polyanilines was 9,it was in critical stable state
