The present invention relates to a sulfur-carbon composite, a method for manufacturing the same, a positive electrode and a lithium secondary battery including the same, wherein the sulfur-carbon composite is a fluorine-based surfactant and sulfur sequentially forming a double coating layer on the surface of the carbon material. 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 gradually melts to prevent deterioration of lithium contained in the negative electrode, and the surface energy of the electrolyte is increased. By lowering and improving the positive electrode wettability, the battery life can be improved. |
