Abstract
A cathode composition for a lithium-ion cell or battery of the general formula: LiMnO, wherein the composition is in the form of a single phase having a rock salt crystal structure such that an x-ray diffraction pattern of the composition has an absence of peaks below a 20 value of 35; and the value of x is greater than 0, and equal to or less than 0.3. The compound is also formulated into a positive electrode, or cathode, for use in an electrochemical cell.
