Ab initio study of doping effects on LiMnO2 and Li2MnO3 cathode materials for Li-ion batteries

The influence of 10 cationic (Mg, Ti, V, Nb, Fe, Ru, Co, Ni, Cu and Al) and 2 anionic (N and F) dopants on the phase stability, redox potential, ionic and electronic conductivity of both Li2MnO3 and LiMnO2 phases have been investigated using density functional theory.
