A special nanocomposite graphite intercalation compound (referred to as GIC) was studied to investigate the characterization, synthesis and application of GIC nanostructures. The results show that the order structure of GIC nanocomposites can be characterized by X-ray diffraction and Raman scattering, and the inter-layer spacing (Ic) can be calculated. The parameters of electrochemical intercalation reaction can be used to synthesize GIC nanocomposite Materials; The electrochemical impedance spectroscopy analysis of the intercalation reaction is a charge in the electrolyte migration, adsorption at the graphite / solution interface and diffusion between the graphite layer process
