Positive electrode active material for lithium secondary battery, method for preparing the same and lithium secondary battery comprising the same

Abstract

A positive electrode active material comprising at least one secondary particle comprising an agglomerate of primary macro particles, a method for preparing the same and a lithium secondary battery comprising the same. According to an embodiment of the present disclosure, it is possible to improve the electrical conductivity of the positive electrode active material surface by coating a conductive carbon material on the surface of the secondary particle. Accordingly, it is possible to provide a nickel-based positive electrode active material with improved life performance by minimizing conductive network losses after cycles.
