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-based coating layer formed on a surface of the positive electrode active material layer. The two types of positive electrode active materials are each represented by Chemical Formula 1 below. The carbon-based coating layer includes a sphere-type conductive material and a binder, where the binder is included in an amount of 5 parts by weight or more and less than 10 parts by weight with respect to 100 parts by weight of the carbon-based coating layer.
