Abstract

Disclosed are a cathode active material for secondary batteries and a lithium secondary battery including the same. More particularly, a cathode active material for secondary batteries having an operating voltage area of 2.50 V to 4.35 V, including a lithium cobalt-based oxide and a surface-treated lithium nickel-based oxide and having high rolling density by a bimodal form in which an average diameter of the cobalt-based oxide and an average diameter of the lithium nickel-based composite oxide are different, and a lithium secondary battery including the same are disclosed.
