【Abstract】 Graphite intercalation compound (GIC) is a new kind of nano composite material. The characterization, synthesis and application of GICs were investigated in this study. The stage structure was characterized and the identity period along the caxis, I c, was analyzed by XRD and Raman scattering spectrum. The synthesized GIC structure could be controlled by controlling the electrochemical parameters such as current, potential and electric charge. A.C. impedance analysis results showed that electrochemical intercalation is a process of charge transfer, adsorption and diffusion of intercalates.更多还原
