A Li-C interatomic potential function was deduced from experimental molecular data and, via a lattice simulation technique, was used to calculate the energies of this first-stage graphite intercalate. A vacancy mechanism for the migration of Li+ ions within a Li layer was proposed. The activation energy for migration was calculated to be 0.18eV.
