摘要： Provided herein are a positive electrode for a secondary battery and a secondary battery including the same. The positive electrode includes a positive electrode active material layer including a positive electrode active material, a conductive material, and a dispersant, wherein the conductive material includes bundle-type carbon nanotubes, units of which have an average strand diameter of 15 nm or less, and the positive electrode active material layer has a packing density of 3.0 g/cc or more, and has an average pore diameter of 0.1 µm to 0.5 µm at the packing density when a pore size distribution is measured by mercury intrusion porosimetry, and thus may exhibit excellent electrolyte wetting properties. As a result, when the positive electrode is applied to a battery, wetting time of the positive electrode is shortened, and an area of the positive electrode that is not filled with an electrolyte is reduced, resulting in enhanced battery performance.
