NOVELTY - Preparation of a graphene/lithium titanium phosphate (LiTi2(PO4)3) lithium battery cathode material comprises dissolving polyvinyl alcohol in deionized water, placing in a 80 degrees C water bath, adding lithium carbonate, monoammonium phosphate, and titanium dioxide, stirring to completely dissolve, pre-calcining to form solid, drying and grinding it to obtain a precursor, placing the precursor in a tubular furnace, under the protection of argon atmosphere, heating to 900-950 degrees C, preferably 930 degrees C at 8-12 degrees C/minute, preferably 10 degrees C/minute, and keeping the temperature for 8-12 hours to obtain a composite; plating the composite surface with a hydrogenated metal film having a thickness of 0.2-0.8 mu m; pre-heating to 500-800 degrees C, introducing carbon source gas, heating to 900-1200 degrees C, cooling to room temperature, taking out, removing metal by dipping in dilute acid, washing, and drying at 80 degrees C for 24 hours. USE - Method for preparing a graphene/lithium titanium phosphate (LiTi2(PO4)3) lithium battery cathode material. ADVANTAGE - The lithium battery cathode material has improved conductivity, high-current charging performance, specific capacity of 85%, and prevent generation of the side reaction of electrode material and water, and has improved electrochemical performance and stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene/LiTi2(PO4)3 lithium battery cathode material.
