| 摘 要： | 采用化学法合成了聚苯胺/活性炭(PANi/C)和聚苯胺/石墨(PANi/G)复合材料,并研究了其电化学性能.在合成过程中,加入石墨或活性炭均可提高PANi的产率,尤其加入活性炭.所获得的PANi/C、PANi/G复合物的电导率高于聚苯胺与活性炭(PANi+C)、聚苯胺与石墨(PANi+G)混合物及PANi的电导率,其中加入石墨的PANi/G复合物电导率明显增大.以PANi、PANi/G和PANi/C作为Zn-PANi二次电池阴极材料,其放电比容量分别为74.1 mAhg-1、101.3 mAhg-1和118.7mAhg-1,电池库伦效率达90-100%.

| Abstract: | Polyaniline/carbon(PANi/C) and Polyaniline/Graphite(PANi/G)composites were synthesized by the chemical method and their electrochemical performances were investigated in this study.The yield of PANi was improved by adding graphite or activated carbon in the process of synthesis,especially activated carbon.The conductivities of PANi/C and PANi/G composites obtained were high than that of PANi+C,PANi+G and PANi,and the conductivity of PANi/G composite was significantly increased.Using PANi,PANi/G and PANi/C as cathode materials of the Zn-PANi secondary battery,their discharge specific capacity were 74.1 mAhg-1、101.3 mAhg-1 and 118.7mAhg-1,respectively,and the columbic efficiency of the battery was 90-100%. |
