▎ 摘  要

NOVELTY - Graphene-coated porous red phosphorus and conductive carbon composite material comprises red phosphorus and conductive carbon composite material. The red phosphorus and conductive carbon composite material has at least one red phosphorus particle and conductive carbon particles attached to surface of red phosphorus. The surface of red phosphorus particle has porous structure. The red phosphorus and conductive carbon composite material is coated on the outside with at least one layer of graphene. USE - Graphene-coated porous red phosphorus and conductive carbon composite material used as anode material for alkali metal ion battery (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-coated porous red phosphorus and conductive carbon composite material comprising placing red phosphorus and conductive carbon in ball mill tank, filling with inert gas, ball milling to obtain red phosphorus and conductive carbon composite material, oxidizing red phosphorus and conductive carbon composite material, washing, drying to obtain porous red phosphorus and conductive carbon composite material, uniformly dispersing porous red phosphorus and conductive carbon composite material in dispersion of graphene oxide, reducing the solution by adding reducing agent, filtering the reduced liquid, washing and drying.
