Abstract

A positive electrode active material includes: core particles including a lithium nickel-based composite oxide having a nickel content (e.g., amount) of at least about 80 mol% based on 100 mol% of a total metal excluding lithium in the lithium nickel-based composite oxide; and a coating layer disposed on a surface of each core particle and including aluminium, wherein the core particles are each in a form of a secondary particle in which a plurality of primary particles is agglomerated, an aluminium content (e.g., amount), based on total 100 at% of nickel, cobalt, and aluminium is about 10 at% to about 15 at% as measured by energy profiling energy dispersive spectroscopy (EP-EDS) on a surface of a positive electrode active material particle including the core particle and the coating layer.
