Embodiments of the present disclosure relate to a cathode active material for lithium secondary battery including lithium-transition metal composite oxide particles. In the lithium-transition metal composite oxide particles, a (105) plane FWHM ratio measured through in-situ X-ray diffraction (XRD) and defined by Equation 1 is less than or equal to 600%. The life characteristics of a lithium secondary battery can be improved by preventing deformation of a lattice structure and/or crystal structure within the lithium-transition metal composite oxide particles.
