Preparation and Application of Graphite Intercalation Compounds

This paper introduced research on the preparation of graphite intercalation compounds using chemical and electrochemical methods and the characterizations of graphite intercalation compounds synthesized with different intercalants are discussed in it. We also studied the principle of intercalation reactions and the main factors influencing intercalation reactions and characterizations of graphite intercalation compounds. The methods of decreasing sulfur content and ash content of expansible graphite and increasing the volume of expandsion were talked about. The diverse properties of graphite intercalation compounds suggest a number of applications of these materials to mechanical, electrical and chemical engineering process. Graphite intercalation compounds can be made as battery and electrode materials and other materials to seal up and give out heat. They have other applications such as chemical catalytic applications, conductivity applications, et al. We made a summary.
