Abstract

Lithium and molybdenum do not form binary phases under thermodynamic control, but they might do under kinetic control upon lithiation of MoS 2 . High Lithiation of MoS 2 can either lead to high-lithiated phases [1] or form Li-Mo phases at the lithiation point at which decomposition in Li 2 S and elemental molybdenum can occur. First-principles crystal structure prediction calculations suggest that the LiMo, monoclinic structure, and Li 2 Mo, either orthorhombic or tetragonal structures, can be formed under kinetic control as co-products of the overall process of lithiation of MoS 2 . The computed enthalpies of formation of the Li-Mo phases vary considerably if the long-range dispersion interactions are accounted in for the elemental lithium and molybdenum.
