Claim 0:
1. A cathode active material for a lithium secondary battery comprising a lithium composite oxide particle that contains lithium and transition metals including nickel,
wherein a molar ratio of nickel in the transition metals contained in the lithium composite oxide particle is 0.5 or more,
wherein the lithium composite oxide particle satisfies Equation 1 and Equation 2:

1.0≤A(003)/A(104)≤1.5  [Equation 1], wherein, in Equation 1, A(003) is an area of a peak corresponding to a (003) plane in an X-ray diffraction (XRD) analysis graph, and A(104) is an area of a peak corresponding to a (104) plane in the XRD analysis graph,

7.0≤A(104)/A(105)  [Equation 2]

wherein, in Equation 2, A(104) is the area of the peak corresponding to the (104) plane in the XRD analysis graph, and A(105) is an area of a peak corresponding to a (105) plane in the XRD analysis graph.
