Abstract: A composite positive active material includes a lithium nickel cobalt aluminum composite oxide. A full width at half maximum (FWHM) of a peak of a (104) plane of the lithium nickel cobalt aluminum composite oxide is 0.15 or less and an FWHM of a peak of a (108) plane of the lithium nickel cobalt aluminum composite oxide is 0.15 or less, the peaks being obtained by X-ray diffraction analysis using a CuKα X-ray. A method of preparing the composite positive active material, and a lithium secondary battery including a positive electrode including the composite positive active material are disclosed.
