Abstract

The present invention relates to a positive electrode active material for a lithium secondary battery, and a lithium secondary battery including the same, and the positive electrode active material includes lithium cobalt oxide particles. The lithium cobalt oxide particles include lithium cobalt oxide having a Li/Co molar ratio of less than 1 in the particles. Good rate property and life property may be obtained without worrying on the deterioration of initial capacity property.
