Abstract: A graphite material and corresponding methods of fabricating the graphite material from graphene nanoribbons are described. The graphite material is composed of a multiplicity of graphene nanoribbons which are randomly layered on each other. The graphene nanoribbons are less than 0.4 nm thick, 5 nm wide, and 20 nm long. One variant of the method of fabricating the graphite material includes preparing graphene nanoribbons, suspending the graphene nanoribbons in a solvent, and then drying the suspension to fabricate the graphite material and to drive off the solvent.

Abstract: Random graphite which is a type of graphite comprising three-dimensionally random graphene layers, and a fabrication method thereof at a low temperature as below 100° C. are disclosed. Random graphite may have a large volume of an empty space due to the feature of the presence of the three-dimensionally random graphene nanoribbons. Thus, it can be applied to Graphitic Intercalation Compound (GIC) such as electrodes for Li-ion battery.
