NOVELTY - A lithium iron phosphate/graphene composite preparing method involves dissolving iron and phosphorus compound and lithium compound in water, adding an appropriate amount of complexing agent to ensure there is no precipitate generate, regulating the solution to weak acid or neutral using weak acid and weak alkali, followed by dispersing in aqueous graphene oxide to obtain a mixed solution. The mixed solution is dried by calcining to obtain the finished product. USE - Method for preparing lithium iron phosphate/graphene composite for use as lithium ion battery positive pole material. ADVANTAGE - The method enables preparing lithium iron phosphate/graphene composite with high purity, uniform compound and excellent electrochemical properties, in simple, easy and cost effective manner.
