Abstract
In the method for making graphene, an electrolyte solution is formed by dissolving an electrolyte lithium salt in an organic solvent. Lithium ions are separated out from the electrolyte lithium salt in the electrolyte solution. Metal lithium and graphite are disposed in the electrolyte solution, and the metal lithium and the graphite are in contact with each other. In the electrolyte solution, lithium ions and organic solvent molecules jointly insert between adjacent layers of the graphite to form a graphite intercalation compound. The graphene is peeled off from the graphite intercalation compound.

A method for making graphene, the method comprising:
- forming an electrolyte solution by dissolving an electrolyte lithium salt in an organic solvent, wherein lithium ions are separated out from the electrolyte lithium salt in the electrolyte solution;
- disposing metal lithium and graphite in the electrolyte solution, wherein the metal lithium and the graphite are in contact with each other, thereby 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.
