LITHIUM-CONTAINING PARTICLE COATINGS FOR POSITIVE ELECTROACTIVE MATERIALS

A positive electrode material is provided. The positive electrode material includes an electroactive material core and an electrochemically active coating that surrounds the electroactive material core. The electroactive material core includes LiMO, where 0≤x≤0.5 and M is selected from the group consisting of: nickel (Ni), manganese (Mn), iron (Fe), tungsten (W), molybdenum (Mo), vanadium (V), zirconium (Zr), niobium (Nb), aluminum (Al), magnesium (Mg), and combinations thereof. The electrochemically active coating includes LiM′O, where 0≤x≤0.2 and M′ is selected from the group consisting of: nickel (Ni), manganese (Mn), iron (Fe), tungsten (W), molybdenum (Mo), vanadium (V), zirconium (Zr), niobium (Nb), aluminum (Al), magnesium (Mg), and combinations thereof. The electrochemically active coating is a distinct composition from the electroactive material core.
