Beschreibung
Zusammenfassung:	A composite cathode active material, a cathode including the composite cathode active material, and a lithium battery including the cathode are provided. The composite cathode active material includes a core including a lithium metal oxide and a coating layer on the core, wherein the lithium metal oxide includes two or more transition metals including nickel (Ni), an amount of Ni within one mole of the two or more transition metals included in the lithium metal oxide is about 0.65 mol or greater, the coating layer includes LiF, and a resistance of the composite cathode active material is lower than that of the core.
