Positive Electrode Material, and Positive Electrode and Lithium Secondary Battery Which Include the Same

Abstract

A positive electrode material may include a first positive electrode active material in a form of a single particle and a second positive electrode active material in a form of a secondary particle. The second positive electrode active material may have a larger average particle diameter (D50) than the first positive electrode active material. Additionally, when a pressure of 6,500 kgf/cm2 is applied to the positive electrode material, a volume of particles having a particle diameter of 1 μm or less relative to a total volume of particles present in the positive electrode material may be 10% or less.
