    摘要: A process for modifying a surface chemistry of a cathode active material includes providing a powder of the cathode active material, wetting the powder of cathode active material with an efficient amount of a solution to form a mixture, and baking the mixture to obtain a surface modified cathode active material, wherein: the cathode active material has a formula of LiNixMnyCo1-x-yO2, wherein 0≤x≤1, 0≤y≤1, and 0≤x+y≤1; the solution comprises a solvate and a solvent; and the solvate comprises H3BO3, H3PO4, a phosphate salt, a hydrogenphosphate salt, a dihydrogenphosphate salt, or a combination of any two or more thereof.
