Paper Title:
Electrochemical Performance of Li3V2 (PO4)3/C Cathode Material Prepared by Soft Chemistry Route
  Abstract

Monoclinic Li3V2 (PO4)3/C cathode material has been synthesized by soft chemistry route and the electrochemical performance of this material was investigated. The structure of the particles was characterized by X-ray diffraction (XRD). The Li3V2 (PO4)3/C composite exhibits good cycling performance and excellent rate capabilities when cycled between 3.0 and 4.3 V. At 1C rate, the cell displays a reversible capacity of 117 mAh/g and retains 98.1 % of its initial discharge capacity after 50 cycles. At the high rate of 5C, the capacity could reach 109 mAh/g, corresponding to 93 % of that at 0.5C. Electrochemical impedance spectroscopy (EIS) technique was used to analyze the chemical diffusion coefficient of Li.
