Beschreibung
Zusammenfassung:	Provided are a composite cathode active material, a cathode and a lithium battery which include the same, and a method of manufacturing the composite cathode active material. The composite cathode active material includes: a 1st core including a first lithium transition metal oxide; a 2nd core including a second lithium transition metal oxide; and a shell over a surface of at least one selected from the 1st core and the 2nd core, wherein the shell includes at least one first metal oxide, a first carbon-based material, and a second carbon-based material, wherein the first metal oxide is included inside a matrix of the first carbon-based material, the first metal oxide is represented by Formula MaOb (0
