▎ 摘　　要

NOVELTY - A graphene is prepared by providing graphite raw material, inserting metal compound between graphite layers to obtain graphite layer and peeling off graphite intercalation compound. USE - Method for preparing graphene (claimed). ADVANTAGE - The method has wide availability of raw material sources, has low cost, and is simple. The product performance is stable and is suitable for industrial production. DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram illustrating a preparation method of graphene. (Drawing includes non-English language text).
