NOVELTY - A lithium vanadium phosphate/carbon composite material is obtained by taking furan and polyvinyl alcohol as carbon sources, adding a Super P conductive carbon material into the carbon sources and utilizing hydrothermal process to make the carbon source uniformly distributed between the vanadium lithium phosphate particle and calcining.    USE - Lithium vanadium phosphate/carbon composite material for use as a cathode of a secondary lithium ion battery (claimed).    ADVANTAGE - The composite material has high-multiplying-power charging/discharging characteristics and better cyclic stability, and can be prepared in a simple and easy manner.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a lithium vanadium phosphate/carbon composite material, which involves preparing aqueous solution of lithium carbonate, vanadium pentoxide, ammonium dihydrogen phosphate and oxalic acid, adding furan solution and 5-10 wt.% polyvinyl alcohol solution or taking vanadic oxide water solution according to the volume ratio of oxalic acid aqueous solution to obtain mixed solution A, mixing lithium carbonate aqueous solution and ammonium dihydrogen phosphate aqueous solution into mixed solution A to obtain mixed solution B followed by adding the mixed solution A to obtain the vanadium lithium phosphate mixing water solution, taking furan solution or polyvinyl alcohol solution, slowly adding the vanadium lithium phosphate mixed solution to obtain mixed solution C, adding 1-30 wt.% conductive carbon material, carrying out hydro-thermal treatment to the mixed solution C at 120-200 degrees C for 1-20 hours to obtain the vanadium lithium phosphate/carbon powder, and drying at 700-850 degrees C to prepare a vanadium lithium phosphate/carbon composite material.    DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for preparing lithium vanadium phosphate/carbon composite material.'(Drawing includes non-English language text)'
