Abstract

A positive electrode active material includes a first positive electrode active material including a first lithium nickel-cobalt-based composite oxide doped with at least one of B, W, Y, and Mo, the first positive electrode active material being in a form of secondary particles that are formed by agglomerating a plurality of primary particles are agglomerated, with at least a portion of the primary particles having a radial arrangement structure. The positive electrode active material also includes a second positive electrode active material including a second lithium nickel-cobalt-based composite oxide doped with at least one of Zr, Sr, Ce, and Ta, with the second positive electrode active material being in a form of single particles.
