▎ 摘　　要

NOVELTY - The method involves adding ammonium bifluoride aqueous solution to iron nitrate of ethanol solution and stirred. A precipitate is centrifuged and collected after finishing reaction. A precursor is precipitated and dried. The dried sample is placed in a quartz boat and put in a tubular furnace to obtain iron fluoride nano-particle. An iron fluoride/graphene film is prepared and ultrasonically dispersed in deionized water to obtain dispersion liquid. Graphite oxide solution is dispersed with mixed liquid. The graphene film is taken off from a filter film to obtain an anode material. USE - Power lithium ion battery anode material preparation method. ADVANTAGE - The method enables preparing a power lithium ion battery anode material in simple preparation process, better ductility and flexible processing performance, and large scale industrial production and improving lithium ion battery specific capacity of a lithium ion anode material by avoiding forming of particle agglomeration. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a power lithium ion battery anode material preparation method.'(Drawing includes non-English language text)'
