▎ 摘　　要

NOVELTY - The material has lithium iron phosphate nanometer particle structure whose outer surface is provided with nano carbon nano particles. A nano carbon nano-particle coating is coated on an outer surface of the nanometer particle structure and provided with a graphite alkene aggregate molecular graphene single chip. Diameter of nano-lithium iron phosphate crystal grain is about 1-100 nm. A surface of graphite alkene is attached with nano-lithium iron phosphate grains. USE - Phosphate composite material for a lithium iron battery. ADVANTAGE - The material has better performance, and ensures that a lithium iron phosphate grain can fast charging and discharging. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium iron phosphate composite material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a phosphate composite material.
