The nature of electric charge carriers of Lithium-montmorillonite at low water content has been investigated using density functional theory (DFT) calculation. Results show that in the presence of H2O molecule, the Li easily migrates from the MMT surface to a distance above the surface with the barrier for Li migration of 0.09 eV. We found the possibility of Li as charge carrier in the H2O/Li-montmorillonite.
