The composites of Li3V2(PO4)3/C (noted as LVP/C) and Li3V2(PO4)3-V2O3/C (noted as LVP-V/C) are prepared by a rheological phase reaction (noted as RPR) process for anode material. The synthesized samples are measured by the X-ray diffraction (XRD) technique. The content of the carbon in the composite is detected by the thermogravimetric (TG) analysis. The morphologies of powders are observed by the scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The electrochemical properties of the samples as anode material are tested by the battery testing system. The LVP-V/C composite behaved better electrochemical performances than those of LVP/C as an anode material. The reasons that LVP-V/C behaved outstanding electrochemical properties are discussed also. Based on its electrochemical performances, the LVP-V/C composite may be a potential anode material for rechargeable lithium batteries.
