NOVELTY - A lithium titanate/graphene composite electrode material comprises carbon-coated titanium dioxide, 1.0-15 wt.% graphite and lithium source, where molar ratio of lithium to titanium is 0.8-0.88:1. USE - Lithium titanate/graphene composite electrode material for a lithium ion battery. ADVANTAGE - The material has simple combination process, and is easy to manufacture. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a lithium titanate/graphene composite electrode material, involves mixing, stirring and heating 4-6:1 ratio ethanol and water at 100-150 degrees C for 1-2 hours, evaporating solvent to prepare a product, drying the product at 400-600 degrees c for 5 hours to obtain a black carbon-coated titanium dioxide fine powder, preparing graphene, compositing lithium source and graphene with titanium dioxide through ball-milling process at 200-400 degrees C for 2-6 hours, drying the mixture, carrying out heat treatment, and controlling temperature at 700-850 degrees C for 8-12 hours to obtain a lithium titanate/graphene composite electrode material.
