Abstract:
A cathode active material for a lithium secondary battery includes a lithium metal oxide particle, and an organic poly-phosphate or an organic poly-phosphonate formed on at least portion of a surface of the lithium metal oxide particle. Chemical stability of the lithium metal oxide particle may be improved and surface residues may be reduced by the organic poly-phosphate or the organic poly-phosphonate.
