ABSTRACT:
Disclosed is a positive active material for a lithium rechargeable battery, a method of preparing the same, and a lithium rechargeable battery comprising the same. The positive active material has an I(003)/I(104)intensity ratio of between 1.15 to 1 and 1.21 to 1 in an X ray diffraction pattern using CuKα ray, wherein I(003)/I(004)is the X-ray diffraction intensity of the (003) plane divided by the X-ray diffraction intensity of the (104) plane. The compound is represented by the formula:in-line-formulae description="In-line Formulae" end="lead"?LixNiyCozMn1−y−z−qXqO2in-line-formulae description="In-line Formulae" end="tail"?wherein x≧1.05, 0<y<0.35, 0<z<0.35, X is Al, Mg, Sr, Ti or La, and 0≦q<0.1.
