摘要
A comprehensive theoretical description is developed for the structural and elastic properties of the first stage alkali metal graphite intercalation compounds and for pure graphite. We use a simplified density functional theory based on the Thomas Fermi approximation which avoids the excessive labor of a full quantum mechanical calculation but which has been shown to be reliable for a wide class of solids. The assumption is made that no chemical bonds are formed between the intercalant and the carbon host, that the intercalant is fully ionized, and that the excess charge distributes itself uniformly on the graphite planes. We verify this last assumption using an effective mass calculation. Results are obtained for the equilibrium lattice constants, compressibility, shear modulus, zone center phonon frequencies, alkali metal diffusion constants, and intrinsic alkali-alkali interactions. We obtain trends which are in good agreement with experiment. These properties are found to be determined primarily by the classical Coulomb forces operating between the charged constituents. We find the the Li compound to be quite distinct from the heavier alkali compounds, and we ascribe this difference primarily to the much greater compactness of the Li ion. We use out density functional results to construct a simple thermodynamic model for the phase diagram of Li graphite. Inclusion of the effect of the periodic graphite potential on the alkali ions is crucial to obtaining good agreement with experiment.
