▎ 摘　　要

NOVELTY - Lithium-ion battery pre-lithiated silicon carbon multilayer composite anode material comprises an amorphous carbon matrix, a pre-lithiated silicon oxide particles and a graphene material. The graphene material is uniformly coated on outer surface of pre-lithiated silicon oxide to form composite particles. The composite particles are uniformly dispersed in amorphous carbon matrix. USE - Used as lithium-ion battery pre-lithiated silicon carbon multilayer composite anode material. ADVANTAGE - The anode material has good mechanical performance, high conductivity, high initial coulombic efficiency and stable cyclic performance. DETAILED DESCRIPTION - AN INDEPENDENT CLAIMS is included for preparing the lithium-ion battery pre-lithiated silicon carbon multilayer composite anode material, comprising sintering silicon dioxide raw material with lithium-containing ionic liquid to achieve pre-lithiation, and to obtain prelithiated silicon oxide particles, then supporting the catalyst precursor, growing graphene material on surface of pre-lithiated silicon oxide by chemical vapor deposition, then fusing with carbon source and heat-treating. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the lithium-ion battery pre-lithiated silicon carbon multilayer composite anode material.
