Abstract

A positive electrode active material includes a first positive electrode active material having an average particle diameter (D₅₀) in a range of 11 µm to 20 µm and in a form of secondary particles in which a plurality of primary particles are agglomerated; a second positive electrode active material having D₅₀ in a range of 5 µm to 10 µm and in a form of secondary particles in which a plurality of primary particles are agglomerated; and a third positive electrode active material having D₅₀ in a range of 1 µm to 7 µm and in a form of single particles; wherein the third positive electrode active material is in an amount in a range of 5 wt% to 20 wt% based on 100 wt% of the first positive electrode active material, the second positive electrode active material, and the third positive electrode active material.
