Abstract
Provided are a cathode active material composition including an xLiMO.(1−x)LiMeOcomposite (where 0<x<1, and M and Me represent metal ions and may be the same or different from each other) and a conductive polymer material, and a secondary battery including the cathode active material composition in a cathode. Since the conductivity of the secondary battery of the present invention may be improved, the cathode active material composition may improve life characteristics, output characteristics, and rate capability of the secondary battery.
