Lattice-simulation investigation of the migration of lithium inC6Li

Abstract
A lithium-carbon interatomic potential function is calculated from molecular experimental data and, applying a lattice-simulation method, is used to compute the energies of the first-stage graphite intercalate C6Li. A vacancy mechanism for the migration of a Li+ ion within a lithium layer is proposed, involving a calculated activation energy for migration of 0.18 eV.
