▎ 摘　　要

NOVELTY - Preparing lithium iron phosphate/graphene composites material comprises mixing lithium iron phosphate and the graphene in a mass ratio of 8-100:1, then taking N-methyl-2-pyrrolidone as the dispersant, then ball milling for 1-8 hours and drying at 30-130 degrees C for 1-10 hours and then calcining at 500-900 degrees C under nitrogen for 8-30 hours to obtain final product. USE - The method is useful for preparing lithium iron phosphate/graphene composites material (claimed). ADVANTAGE - The method has simple preparation process and low production cost; and the composite material has excellent electrical conductivity.
