▎ 摘　　要

NOVELTY - Intercalated composite comprises iron fluoride grain and carbon layer. The iron fluoride particle is inserted between the interlayer structures of the carbon layer. The carbon layer comprises carbon fluoride and carbon body which is not fluorinated. The fluorinated gas is nitrogen trifluoride, phosphorus pentafluoride, sulfur hexafluoride or fluorine gas. The carbon material is natural graphite, expanded graphite or graphene micro sheet. USE - The intercalated composite material is used as material for anode lithium (claimed). ADVANTAGE - The intercalated compound has high specific capacity and high stable cycle performance, and controls the fluorination degree of the carbon layer in the compound. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of intercalated compound. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic diagram of the structure of an intercalated composite material as material for anode lithium.
