Preparation method of lithium iron phosphate/graphene composite material

The invention discloses a preparation method of a lithium iron phosphate/graphene composite material. The preparation method comprises the following steps of adding graphene and riboflavin sodium phosphate into a solvent; treating by ultrasonic waves, stirring, and uniformly dispersing; respectively dissolving a complexing agent, a lithium source compound and an iron salt compound into a solution, then sequentially adding into a graphene dispersing liquid, and reacting, so as to obtain the lithium iron phosphate/graphene composite material; uniformly mixing the obtained lithium iron phosphate/graphene composite material and a carbon source in a ball milling way, drying, and calcining for 3 to 24h at constant temperature of 600 to 850 DEG C under the inert gas protection atmosphere, so as to obtain the graphene-modified lithium iron phosphate/carbon composite material. The preparation method has the advantage that the riboflavin sodium phosphate is dispersed into the graphene to form a surfactant, and can also be used as a phosphor source in the generation process of the lithium iron phosphate. The prepared graphene-modified lithium iron phosphate/carbon composite material can be used as the cathode material of a lithium ion battery, so that the electrochemical properties, particularly the cyclic stability at high rate, of the battery can be obviously improved.
