Abstract
A cathode active material for a lithium secondary battery includes a lithium metal oxide secondary particle core formed by agglomerating lithium metal oxide primary particles; and a shell formed by coating the secondary particle core with barium titanate and metal oxide. This cathode active material allows making a lithium secondary battery having improved safety, particularly in thermal stability and overcharging characteristics.
