Lithium Cobalt-Based Positive Electrode Active Material, Preparation Method Thereof, Positive Electrode Including Same, and Secondary Battery Including Positive Electrode
摘要：
A method for preparing a lithium cobalt-based positive electrode active material and a positive electrode active material prepared by the method are provided. The method includes dry-mixing and then heat treating a lithium cobalt oxide particle represented by Formula 1 and one or more lithium metal oxide particle selected from the group consisting of lithium aluminum oxide, lithium zirconium oxide, and lithium titanium oxide.
