The present invention relates to a positive electrode for a lithium secondary battery and a lithium secondary battery including the same, wherein the positive electrode includes a positive electrode active material capable of reversible intercalation / deintercalation of lithium and a conductive agent attached to a surface of the positive electrode active material. Conductive agent / anode active material composite; And a binder, wherein the conductive agent includes a first conductive agent having a specific surface area of 500 to 1500 m 2 / g and a second conductive agent having a specific surface area of 100 m 2 / g or less.n n n When slurry mixing for the production of the electrode plate using the composite of two or more kinds of the conductive agent and the positive electrode active material, the binder content in the electrode plate can be reduced by adding only a binder without additionally adding a conductive agent, and the conductive coating layer The non-conductive binder can be contacted to minimize the increase in electrical resistance due to the binder, thereby providing a positive electrode with a reduced anode resistance and an increased mixture density.n n n n Conductive agent, positive electrode active material, composite, lithium secondary battery, positive electrode |
