  "textContent": "The present invention relates to a sulfur-carbon composite, a preparation method thereof, a positive electrode, and a lithium secondary battery comprising the same, wherein the sulfur-carbon composite has a fluorine-based surfactant and sulfur sequentially forming a double coating layer on the surface of the carbon material, and thus when the sulfur-carbon composite is applied to a positive electrode of a lithium secondary battery, for example, a lithium-sulfur secondary battery, the fluorine-based surfactant can be slowly dissolved to prevent deterioration of lithium contained in the negative electrode, and the surface energy of the electrolyte solution can be lowered to improve the wettability of the positive electrode, thereby improving the lifetime of the battery.",
