| 摘 要： | 以石墨烯和纳米硅颗粒为起始原料,苯胺为单体,植酸为掺杂剂,过硫酸铵为氧化剂(引发剂),通过超声波的作用成功原位合成了具有三明治纳米结构的Si/RGO@PANI锂离子电池负极材料。石墨烯片层与导电聚苯胺与纳米硅颗粒构成的夹心结构可形成有效的导电网络,且具有优异的结构稳定性,能够有效缓解硅在嵌锂/脱锂过程中产生的巨大体积效应,表现出良好的循环性能和倍率性能。电化学性能测试表明,这种Si/RGO@PANI三明治纳米结构复合材料适合作为一种优良的锂离子电池负极材料。

| Abstract: | A sandwich-like Si/RGO@PANI nanocomposite as anode for lithium ion batteries was successfully in situ prepared under condition of ultrasonication by using graphene and silicon nano particles as precursors, aniline as monomers, phytic acid as a dopant and ammonium persulfate as an oxidizer (initiator). The sandwich structure composed of graphene sheets, conductive polyaniline, and nano silicon particles create an efficient conductive network which can endure the great volume change of silicon and retain structural stability during Li-ion insertion/extraction. The electrodes consisting of this sandwich-like Si/RGO@PANI nanocomposite reveal excellent cyclability and rate capability, and can be considered as an ideal anode material for lithium ion battery. |
