Abstract
A positive electrode material, a positive electrode including the same, and a lithium secondary battery including the same are disclosed herein. In some embodiments, a positive electrode material includes a first positive electrode active material having a larger average particle diameter than a second positive electrode active material, wherein the first positive electrode active material and the second positive electrode active material are each independently a lithium transition metal oxide having a molar ratio of nickel of 80 mol % or more relative to the total molar amount of transition metals in the lithium transition metal oxide, and the positive electrode material satisfies Equation (1):0<{()/}×100≤10 Equation (1):wherein, in Equation (1), A denotes a particle strength of the first positive electrode active material, and B denotes a particle strength of the second positive electrode active material.
