NOVELTY - Preparation of nano lithium iron phosphate/graphene composite material comprises preparing 0.3-3 mol/L lithium hydroxide/ethylene glycol solution and 0.2-2 mol/L phosphoric acid/ethylene glycol solution, dissolving iron sulfide in ethylene glycol, mixing, reacting at 150-200 degrees C for 5-15 hours, cooling, precipitating, centrifuging, drying, adding lithium iron phosphate and graphite oxide in water, mixing, adding hydrazine hydrate, placing in water bath at 70-90 degrees C for 3-10 hours, centrifuging and drying. USE - Method of preparing nano lithium iron phosphate/graphene composite material used for preparing lithium ion battery anode material (claimed). ADVANTAGE - The method is simple, has excellent large-current cycle stability, low energy consumption and low cost.
