▎ 摘　　要

NOVELTY - A split-graphene composite material comprises sheet shaped vinyl chloride uniformly loaded on the graphene sheet. USE - Split-graphene composite material for use as anode material in lithium air battery (claimed). ADVANTAGE - The split-graphene composite material can be prepared with better conductivity, large specific surface area and high catalytic activity (Ko/P) graphene composite material, high specific capacity and better cycle performance in simple and cost-effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing split-graphene composite material, which involves dissolving vanadium salt and graphene under the action of surface active agent and dispersing in the alcohol-water mixed solvent and performing thermal method using solvent to obtain precursor, placing the precursor in the protective atmosphere, carrying out heat treatment at a temperature at more than 900 degrees C to obtain the product.
