▎ 摘　　要

NOVELTY - Graphene material comprises 100 pts. wt. potassium hydroxide, 35-55 pts. wt. active carbon, 4-8 pts. wt. nickel cobalt manganese, 20-40 pts. wt. graphene oxide, 1-5 pts. wt. sodium hydroxide, 4-8 pts. wt. sodium borohydride, 24-28 pts. wt. lithium nitrate, 3-7 pts. wt. triethylene tetramine, 6-10 pts. wt. N,N-diethylhydroxylamine, 5-9 pts. wt. N,N-diethyl ethanolamine, 15-35 pts. wt. ethanol, 10-30 pts. wt. glycol, 5-25 pts. wt. formamide and 2-6 pts. wt. ammonium nitrate. USE - Graphene material for lithium battery (claimed). ADVANTAGE - The graphene material is easy to operate, has stable product quality, yield and wide production, and prepared in simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene material, which involves: (A) weighing raw materials; (B) mixing active carbon and graphene oxide into the reaction kettle with stirrer and thermometer, heating at 300-500 degrees C for 40-60 minutes, adding rest raw material, decompressing, filtering, drying in oven at 75-95 degrees C for 20-40 minutes, washing with ethanol for 3-5 times, drying, crushing into crusher for 50-60 minutes through 200 meshes sieve; and (C) placing in ceramic crucible with cover, placing into tubular furnace at 450-550 degrees C for 1-5 hours, and heating at 600-800 degrees C for 2-6 hours to obtain graphene material.
