Abstract
Provided are a positive electrode active material, a method of preparing the same, and a lithium secondary battery using the positive electrode active material, and more particularly, a positive electrode active material in which a surface of layer-structured lithium transition metal composite oxide is coated with one or more indium-based compounds selected from the group consisting of indium oxides and alloys including indium, a method of preparing the positive electrode active material, and a lithium secondary battery using the positive electrode active material. According to the present disclosure, degradation of cycle characteristics according to repetitive discharge of a battery may be prevented and thermal stability and rate characteristics may be improved.
