摘要
The relation between the compositions of alkali metal-graphite intercalation compounds and the crystallite size of pristine graphite was mathematically analyzed taking into account the in-plane structure and the stacking sequence of the graphite intercalation compounds. It has been found that the atomic ratio of carbon and alkali metal in GICs, C/M (M = Li, K. Rb, and Cs) was approximated by a function of the crystallite size (L(a) and L(c)) and the interlayer spacing (d002) of the pristine graphite. The derived equation shows good agreement with the experimental results previously reported.
