碳源对核壳结构LiFePO4/C纳米复合正极材料性能影响
Effects of carbon resources on electrochemical performance of LiFePO4/C nanocomposites as cathode materials for lithium ion batteries
摘要
Abstract
Nano-sized LiFePO4/C with a core/shell structure was prepared by a two-step procedure,which involved the synthesis of FePO4/polyaniline (PANI) and subsequent thermal calcination in the presence of carbon sources.An initial coating of PANI on FePO4 could protect LiFePO4 nanopaticles from further growth,facilitating the fabrication of the nano-sized LiFePO4/C nanocomposites.Carbon sources,such as sucrose,polyethylene glycol or conductive carbon black,were found to have great effects on size,shape and electrochemical performance of LiFePO4/C nanocomposites.LiFePO4/C nanocomposites fabricated with sucrose as carbon source have relatively uniform sizes and higher contents of carbon,and exhibit the superior electrochemical performance.关键词
