Abstract
The present invention relates a method for producing a graphite intercalation compound (GIC) and to the production of graphene using the same. The method of the present invention comprises the following steps: (a) obtaining alkaline metals or alkaline metal ions, or alkaline earth metals or alkaline metal ions, from alkaline metal salts or alkaline earth metal salts; (b) forming a graphite intercalation compound using the alkaline metals or alkaline metal ions, or the alkaline earth metals or alkaline earth metal ions; and (c) dispersing the graphite intercalation compound so as to obtain graphene. As the method of the present invention uses salts which are inexpensive and safe, graphite intercalation compounds can be easily produced at a low cost, and the graphene can be obtained from the thus-produced compounds, thereby reducing the costs of producing the graphene and enabling the easy mass production of the graphene.
