Beschreibung
Zusammenfassung:	A cathode active material precursor for a lithium secondary battery has a structure of a nickel composite hydroxide. A first peak intensity ratio represented by Equation 1 is 0.5 or more, and a second peak intensity ratio represented by Equation 2 is 0.7 or more. A cathode active material and a lithium secondary battery having a stabilized crystal structure are provided using the cathode active material precursor.
