Positive Electrode for Lithium Secondary Battery and Lithium Secondary Battery Including the Same

A positive electrode includes: a positive electrode active material layer formed on a surface of a positive electrode current collector, including two types of positive electrode active materials with different average particle diameters (D), a conductive material, and a binder; and a carbon nanotube coating layer formed on a surface of the positive electrode active material layer, including carbon nanotubes and a binder: The two types of positive electrode active materials include first positive electrode active material particles which have an average particle diameter (D) of 8 μm to 20 μm and second positive electrode active material particles in the form of a single particle which have a smaller average particle diameter (D) than the average particle diameter (D) of the first positive electrode active material particles, and the positive electrode active material layer and the carbon nanotube coating layer are formed in a thickness ratio of 90:10 to 99:1.
