CATHODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY INCLUDING THE SAME

A cathode active material for a lithium secondary battery includes a lithium-transition metal oxide particle. A crystal index (CI) of the lithium-transition metal oxide particle is 15 or more. A lithium secondary includes a cathode including the cathode active material, and an anode facing the catho...

Beschreibung
Zusammenfassung:A cathode active material for a lithium secondary battery includes a lithium-transition metal oxide particle. A crystal index (CI) of the lithium-transition metal oxide particle is 15 or more. A lithium secondary includes a cathode including the cathode active material, and an anode facing the cathode. The cathode active material and the lithium secondary battery have improved operational reliability and thermal stability.
