Wherein the full width at half maximum (FWHM) of the lithium nickel cobalt aluminum composite oxide with respect to the (104) plane obtained by X-ray diffraction analysis using a Cu-k? Ray is 0.15 or less, And a FWHM of the peak to the surface of 0.15 or less, a process for producing the same, and a lithium secondary battery containing a positive electrode containing the same. |
