NOVELTY - Preparation of lithium iron phosphate/graphene composite material comprises measuring certain volume of high-boiling organic alcohol and ethanol, weighing iron phosphate, lithium carbonate and graphene, mixing, solid-phase ball milling, filtering to separate solid mixture from liquid, adding solid mixture to atmosphere furnace, and heating under non-oxidizing atmosphere. USE - The method is for preparation of lithium iron phosphate/graphene composite material. ADVANTAGE - The method uniformly distributes graphene in lithium iron phosphate that can greatly improve the electronic conductivity of the material, and effectively improves charge-discharge performance of lithium iron phosphate material.
