Beschreibung
Zusammenfassung:A cathode active material for a lithium secondary battery includes a lithium-transition metal composite oxide particle having a single particle shape, and a first coating layer formed on a surface of the lithium-transition metal composite oxide particle. The first coating layer includes a La-Zr-O compound. Life-span and capacity properties are improved by a combination of the lithium-transition metal composite oxide particle having the single particle shape and the first coating layer formed thereon.
