Abstract
The structures of intercalate layer in several metal chloride-graphite intercalation compounds (GICs) were studied by the analysis of extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES). The intercalated CuCl2 in CuCl2-GIC maintains a similar layer structure with long-range-order to that in anhydrous CuCl2 crystal. The structure of intercalated iron chloride in its GIC obtained in FeCl3-KCl molten salt is similar to that in the ternary GICs with iron chloride and nickel chloride, which are synthesized by using either a mixture of FeCl3 and NiCl2 or a FeCl3-NiCl2-KCl molten salt. In these ternary compounds, iron and nickel chlorides intercalated have a long-range-order in their layers and seem to exist in separated domains.Keywords
