Abstract

A positive electrode active material including at least one secondary particle comprising an agglomerate of primary macro particles is provided. A method for preparing the same and a lithium secondary battery containing the same are also provided. The positive electrode active material contains secondary particle with improved resistance by simultaneous growth of the average particle size D50 and the crystal size of the primary macro particle. The positive electrode active material has high crystal density and improved life and resistance characteristics by ensuring the movement path of lithium ions and minimizing defects in the crystal structure of the positive electrode active material.
