▎ 摘　　要

NOVELTY - A graphene aggregate composite material comprises multilayer graphene layer and nanoparticles deposited between different graphene layer. USE - Graphene aggregate composite material used in preparing graphene aggregate energy storage material, lithium ion battery or graphene powder (all claimed). ADVANTAGE - The method ensures sufficient isolation between layers, increases specific surface area, and prevents graphene flake layer formation in post-processing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene aggregate composite material comprising oxidation reacting layered graphite, oxidant and acid solution to obtain graphite oxide, high temperature processing to strip graphite oxide to graphene, obtaining graphene aggregate, high temperature depositing in the presence of gas, and generating nanoparticles between different graphene layer.
