Abstract

A composite positive electrode active material may include a first positive electrode active material including a first lithium nickel-based composite oxide and a second positive electrode active material including a second lithium nickel-based composite oxide, which has an average particle diameter D50 smaller than an average particle diameter D50 of the first positive electrode active material. The first lithium nickel-based composite oxide may include tungsten, aluminum, and boron. An amount of the aluminum in the first positive electrode active material may be from about 0.1 mol% to about 1.45 mol% based on 100 mol% of a total metal, excluding lithium, in the first positive electrode active material. An amount of the boron in the first positive electrode active material may be from about 1.05 mol% to about 2 mol% based on 100 mol% of the total metal, excluding lithium, in the first positive electrode active material.
