Method of Preparing Positive Electrode Material for Lithium Secondary Battery and Positive Electrode Material for Lithium Secondary Battery Prepared Thereby

Abstract

A positive electrode material includes a first positive electrode active material and a second positive electrode active material. The first positive electrode active material has an average particle diameter (D50) of 10 μm to 30 μm and the second positive electrode active material has a smaller average particle diameter than the first positive electrode active material. An equivalent weight of lithium in the first positive electrode active material and an equivalent weight of lithium in the second positive electrode active material are different.
