Lithium cobalt-based positive electrode active material, method for preparing same, positive electrode comprising same, and secondary battery |
| abstract |
The present invention relates to a lithium cobalt-based positive electrode active material including a core portion including a lithium cobalt-based oxide represented by Formula 1 and a shell portion including a lithium cobalt-based oxide represented by Formula 2, wherein the lithium cobalt-based positive electrode active material includes 2500 ppm or more, preferably 3000 ppm or more of a doping element M based on the total weight of the positive electrode active material, and an inflection point does not appear in a voltage profile measured during charging/discharging a secondary battery including the lithium cobalt-based positive electrode active material. |
