A CATHODE FOR HIBRID ELECTRIC VEHICLE WITH IMPROVED ELECTRON CONDUCTIVITY

摘要

The present invention relates to a positive electrode for a secondary battery with high output preventing a capacity loss or overvoltage generation by enhancing electron conductivity, and a secondary battery including the same. The positive electrode includes an active material, a first conductive material and a second conductive material. At least a portion of the surface of the active material is covered by the first conductive material in the positive electrode, and the second conductive material is included in a positive electrode active material layer in a manner of coming into contact with a plurality of positive electrode active materials covered with the first conductive material.
