NOVELTY - Synthesizing graphene/carbon-coated lithium iron phosphate small-scale nanocomposites through aniline polymerization confined effect involves dispersing graphite oxide and ferric iron salt in deionized water, and adding ammonium persulfate and mixing to obtain first solution, dissolving phosphate in deionized water at room temperature, adding aniline, and mixing to obtain second solution, mixing first solution and second solution at room temperature and continuously stirring for 4-12 hours to obtain the precursor material. The prepared precursor material is mixed with the lithium source in solid phase, and then an organic small molecular carbon source is added, and ground uniformly in a protective atmosphere furnace with inert gas and/or a reducing gas, continuously increase the temperature to 550-750 degrees C at temperature increase rate of 5 degrees C per minute for 6 hours, and cooled to room temperature to obtain graphene/carbon coated lithium iron phosphate small-scale nanocomposite. USE - Method for synthesizing graphene/carbon-coated lithium iron phosphate small-scale nanocomposites through aniline polymerization confined effect. ADVANTAGE - The method enables to synthesize graphene/carbon-coated lithium iron phosphate small-scale nanocomposites through aniline polymerization confined effect has good cycle performance.
