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 mA·h/g, 充放电电流密度为100 mA/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 mA·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.

Abstract:

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 mA·h/g(the charge and discharge current density is 100 mA/g) and good cyclic stability(after 300 cycles of charging and discharging, the specific capacity remains above 1400 mA·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.
