▎ 摘　　要

NOVELTY - The method involves preparing carbon-coated lithium iron phosphate powder. A dual-layer graphene sheet is coated with a raw material. Electrolyte solution is added in a reaction container. A tungsten silk is covered on the dual-layer graphene sheet. A cathode is placed in the reaction container. A graphite electrode is inserted into the dual-layer graphene sheet. High offset voltage of the dual-layer graphene sheet is determined. Large graphite granule is removed through water. A graphene modified lithium iron phosphate anode material is obtained. USE - Method for preparing a high capacity graphene modified lithium iron battery phosphate anode material. ADVANTAGE - The method enables improving capacity of the graphene modified lithium iron phosphate anode material and solving carbon-coated and doped problems. DETAILED DESCRIPTION - The reaction container is made of glass or ceramic and plastic material. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a high capacity graphene modified lithium iron battery phosphate anode material.
