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. |
