Abstract
A positive electrode active material for a lithium secondary battery includes a lithium composite transition metal oxide including transition metals including nickel (Ni), cobalt (Co), and manganese (Mn), and the lithium composite transition metal oxide is doped with doping elements including cobalt (Co) and titanium (Ti). The lithium composite transition metal oxide includes at least one lithium layer and at least one transition metal layer including the transition metals, and the lithium layer and the transition metal layer are alternately arranged. The thickness of the lithium layer ranges from 2.146 Å to 2.182 Å, and the thickness of the transition metal layer ranges from 2.561 Å to 2.595 Å.
