NOVELTY - A lithium salt-graphene derivative composite material comprises lithium salt and 5-75 mass% amino-group anthraquinone derivative of graphene. USE - Lithium salt-graphene derivative composite material for a lithium ion battery (claimed). ADVANTAGE - The material improves specific capacity of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a lithium salt-graphene derivative composite material, which involves performing oxidation reaction on graphite, potassium permanganate and concentrated sulfuric acid to obtain oxidized graphite, dissolving the graphite oxide in solvent, adding amino quinine compound and alcohol solution, and processing the reflux reaction at 80 degrees C for 24 hours to obtain the amino-group anthraquinone derivative, mixing the hydrated amino-group anthraquinone derivative with a sufficient amount of the oxidized graphite alkene hydrazine for 5 to 24 hours to obtain graphite alkene of amino-group anthraquinone derivative, mixing the amino-group anthraquinone derivative with lithium salt of graphene and drying the mixture at 80 degrees C under reflux reaction to obtain the lithium salt-graphene derivative composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of a method for preparing a lithium salt-graphene derivative composite material. '(Drawing includes non-English language text)'
