A novel 0.6Li(3)V(2)(PO4)(3)center dot 0.4Li-V-O composite cathode material is synthesized by sol-gel method followed by solvothermal and solid state reaction. The morphology and structure of the composite are characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photo-electron spectroscopy (XPS). The composite particles are well-crystallized and present uniform nanoplate alike. Except Li3V2(PO4)(3) phase, LiV2O5 and VO2 are also present in the composite. The 0.6Li(3)V(2)(PO4)(3)center dot 0.4Li-V-O electrode delivers a discharge capacity of 149.3mAhg(-1) at 50mAg(-1) between 2.0 V and 4.3 V, and has higher rate property than Li3V2(PO4)(3). The diffusion coefficients of Li ions in the composite are in the range of 10(-9.5) -10(-7.5)cm(2) s(-1) obtained from galvanostatic intermittent titration technique (GITT). (C) 2015 Elsevier Ltd.
