摘要

采用简单的原位氧化聚合法，在HClO₄溶液中制备聚苯胺/FeFe(CN)₆［PANI-FeFe(CN)₆］复合材料，制备的复合材料中PANI自组装成管状形貌，FeFe(CN)₆具有完美的面心立方晶格（FCC）结构并在PANI基体中分散良好.PANI-FeFe(CN)₆复合材料作为锂离子电池的正极材料，具有较高的比容量、循环稳定性和电流倍率性能等.PANI-FeFe(CN)₆(80%，质量分数，以下同)复合材料经100次循环后仍保持95.7 mAh/g的放电比容量，表明其具有优良的循环性能.在20、50、100、200和500 mA/g电流密度下，PANI-FeFe(CN)6(80%)比容量分别为95.9、98.8、91.4、83.6和72 mAh/g，明显高于PANI和FeFe(CN)₆ 的比容量.PANI与FeFe(CN)₆组分之间形成的相互作用和复合材料导电性的提高使PANI-FeFe(CN)₆复合材料具有较高的电化学性能，使其成为潜在的新型锂电池正极材料.

聚苯胺 FeFe(CN)₆ 锂离子电池正极材料

Abstract:

Polyaniline/FeFe(CN)₆［PANI-FeFe(CN)₆］composites were prepared by a simple in-situ oxidation polymerization in HClO4 solution.PANI self-assembled into tubular morphology in the prepared composites,while FeFe(CN)₆ with perfect face-centered cubic lattice(FCC) structure and was well-dispersed in the obtained PANI matrix.As the cathode of lithium ion battery,PANI-FeFe(CN)₆composite demonstrates the improved specific capacity,cycling stability and current rate performances.The PANI-FeFe(CN)₆(80%) composite materials maintained a discharge capacity of 95.7 mAh/g after 100 cycles,indicating its excellent cycling performances.Especially,its specific capacities were 95.9,98.8,91.4,83.6 and 72 mAh/g at the currents densities of 20,50,100,200 and 500 mA/g,which was obviously higher than those of PANI and FeFe(CN)₆,respectively.The significantly improved electrochemical performances for PANI-FeFe(CN)₆ composites could be ascribed to the formed interaction between PANI and FeFe(CN)₆ components and the enhanced electrical conductivity,which made it a potential candidate as the cathode of lithium battery.
