1. A positive electrode for a lithium secondary battery comprising:

  • a positive electrode current collector;

    a lower positive electrode active material layer disposed on at least one surface of the positive electrode current collector; and

    an upper positive electrode active material layer disposed on the lower positive electrode active material layer,wherein the lower positive electrode active material layer comprises 90% or more of a sphere-type carbonaceous conductive material as a conductive material,the upper positive electrode active material layer comprises 90% or more of a needle-type carbonaceous conductive material as a conductive material, anda content of the conductive material contained in the lower positive electrode active material layer is larger than a content of the conductive material contained in the upper positive electrode active material layer.
