  "textContent": "A positive electrode for a lithium-sulfur secondary battery includes a positive electrode active material layer having an intaglio pattern formed therein. A method for manufacturing the same, and a lithium-sulfur secondary battery including the same are also provided. The positive electrode active material layer has a porosity of 50 to 65%. The intaglio pattern has a width of 1 to 100 μm and a depth of 30 to 99% based on the thickness of the positive electrode active material layer. The volumetric ratio of the positive electrode active material layer and the intaglio pattern is 4:1 to 40:1. When the positive electrode is applied to a lithium-sulfur secondary battery, the energy density per unit volume can be remarkably improved.",
