Abstract
Provided are a positive electrode active material for a secondary battery, in which, since the positive electrode active material includes a lithium-metal oxide having high-temperature stability and a metal oxide on a surface of a particle and a surface side in the particle, there is no concern about gas generation, because the occurrence of cracks on the surface of the active material is prevented during charge and discharge, and high-temperature storage stability and life characteristics may be improved when the positive electrode active material is used in the battery, and a secondary battery including the same.
