采用界面聚合法制备了高导电性的聚苯胺纳米纤维。将聚苯胺纳米纤维用作锂聚合物电池的活性正极材料。以聚(偏氟乙烯-六氟丙烯)P(VDF-co-HFP)为多孔膜，制备了凝胶聚合物电解质(GPE)，并将其用作组装Li/GPE/聚苯胺电池的电解质材料。通过循环伏安法和充放电循环测试研究了电池的电化学性质。电池第20次最大放电容量为69mAhg(-1)，第100次最大放电容量为48mAhg(-1)，库仑效率为97%。(C)2006爱思唯尔B.V.保留所有权利。
Polyaniline nanofibres of high conductivity were prepared by interfacial polymerization. The polyaniline nanofibres were used as an active cathode material in lithium-polymer cells. Gel polymer electrolyte (GPE) based on the porous poly(vinylidene-co-hexafluoropropylene) P(VdF-co-HFP), membrane was prepared and used as an electrolyte material in assembling Li/GPE/polyaniline cells. The electrochemical properties of the cells were investigated by cyclic voltammetry and charge-discharge cycling tests. The cell delivered a maximum discharge capacity of 69 mAh g(-1) at 20th cycle and 48 mAh g(-1) at 100th cycle with 97% coulombic efficiency. (c) 2006 Elsevier B.V. All rights reserved.
