NOVELTY - Preparing graphene-based lithium iron phosphate anode material, comprises (1) mixing graphene oxide with iron source solution during the preparation of iron phosphate, and subjecting to co-precipitation reaction with phosphoric acid, ammonium phosphate or ammonium dihydrogen phosphate, then washing the reaction product, filtering, vacuum or flash drying, and then calcining and grinding to obtain graphene oxide-iron phosphate composite material, where the amount of graphene oxide added is 1-15% of the amount of iron phosphate, and (2) adding the obtained graphene oxide-iron phosphate composite material, lithium carbonate and glucose into ball mill to grind and disperse evenly, and drying to obtain lithium iron phosphate precursor, then pre-sintering at 250-500 degrees Celsius under hydrogen/argon/nitrogen and other reducing atmosphere for 3-6 hours, sintering at 600-800 degreesC for 6-12 hours and cooling in the furnace to obtain graphene-based lithium iron phosphate anode material. USE - The graphene-based lithium iron phosphate anode material is useful in manufacturing power-type lithium ion batteries. ADVANTAGE - The method improves the dispersibility and uniformity of graphene in the anode material, and thus overcoming the defect that graphene is not easy to disperse in water in the process of preparing anode material.
