NOVELTY - Making graphene, comprises: forming an electrolyte solution by dissolving electrolyte lithium salt in organic solvent, where lithium ions are separated out from the electrolyte lithium salt in the electrolyte solution; disposing metal lithium and graphite in the electrolyte solution, where the metal lithium and the graphite are in contact with each other, thus the lithium ions and organic solvent molecules from the organic solvent jointly gather between adjacent layers of the graphite to form a graphite intercalation compound; and peeling off graphene from the graphite intercalation compound. USE - The method is useful for making graphene. ADVANTAGE - The method: forms graphite intercalation compound by inserting solvated lithium ions between the graphite layers and without oxidizing graphite, thus the distance between the adjacent crystal planes of the graphite is larger than the distance between the adjacent crystal planes of the graphite without the insertion of the solvated lithium ions, and hence bonding force between graphite layers are poor and the graphite layer can be easily peeled off to form graphene; is simple and cost effective, thus easily realizing industrial production of the graphene; and does not require oxidizing agent thus electronic structure and crystal perfection of the graphene are preserved.
