Abstract
The present invention relates to fluorine substituted cation-disordered lithium metal oxides for high capacity lithium-ion battery electrodes suitable for use in lithium-ion rechargeable batteries having a general formula: LiMOF, wherein 0.05≤x≤0.3 and 0<y≤0.3 and M is a transition metal, such as Ti, V, Cr, Mn, Fe, Co, Ni, Zr, Nb, Mo, Sn, Sb, and combinations thereof. The fluorine-substituted cation-disordered materials of the present invention demonstrate improved electrochemical performance, showing high capacity and high voltage. The present invention also relates to methods of making the fluorine-substituted cation-disordered materials.
