✦ Synopsis

Phonon dispersion relations have studied for the first stage ~raphile-lithium intercalation compound C,Li using an angular force model approach. We have used the stacking sequence CaCnCa in the present case.

A good agreement is seen when compared with the experimental results, suggesting that the angular forces play an important role in explaining the phonon spectra of layered structures. We obtain a satisfactory agreement for the elastic constants C, and C,, when compared with experiment.

We report the results of self-consistent band structure calculations for Li&, LiC,\*, and LiCls in idealized crystal structures representing first, second, and third stage intercalation compounds. Results for LiC,\* indicate that 90% of the net excess charge is localized in the region between the tw
