Abstract: CuCl2-graphite intercalation compounds (CuCl2-GICs) were synthesized in molten CuCl2. The effects of the reaction time and the ratios of the reagents on the stage structure, morphology and electrical properties were investigated in detail. The results show that the synthesized products are mainly the CuCl2-GICs with mixed stages of stage 1 and other stages. Small amounts of graphite are also found in the products. When the reaction time increases, the intercalation effects are enhanced. However, the variations of the ratios of the reagents show little effect on the microstructure of the CuCl2-GICs. The morphology observation indicates that the graphite flakes expand after the intercalation and amounts of CuCl2 are found on the edge of the graphite flakes. The EDS elemental analysis demonstrates that the copper chlorides are nonstoichiometry with a lot of [Cl-] deficiency. The electrical conductivity of the CuCl2-GICs improves when compared to those of the original graphite and a maximum of 80% improvement is achieved.
