摘　　要：采用阳极氧化铝(AAO)模板电化学沉积方法,合成了1种新型吡咯-(3,4-乙烯二氧噻吩)(PE)共聚物纳米线阵列薄膜,作为锂离子电池电极材料,其表现出较高的比容量(1426. 1 m A·h/g,充放电电流密度为100 m A/g)和很好的循环稳定性(在充放电循环300圈之后,比容量仍然保持在1400 m A·h/g以上).这种多组分共聚物纳米线阵列有可能成为下一代长寿命、高性能的锂离子电池电极材料而被广泛开发.We adopted the anodic aluminum oxide( AAO) template electrochemical deposition method for synthesis of a new type of copolymer nano array membrane structure as lithium ion battery electrode material.This pyrrole-( 3,4-ethylenedioxythiophene)( PE) copolymer nano-array membrane material has a lot of advantages,such as better electrochemical properties. The specific capacity can reach 1426. 1 m A·h/g( the charge and discharge current density is 100 m A/g) and good cyclic stability( after 300 cycles of charging and discharging, the specific capacity remains above 1400 m A · h/g). Therefore, this multi-component polymer nanowire array may be widely developed for the next generation of long life,high-performance lithium-ion battery electrode materials.
