Abstract
Disclosed is a sulfur-carbon composite, and a positive electrode for a lithium secondary battery and a lithium secondary battery including the same. More specifically, since the carbon contained in the sulfur-carbon composite includes carbon of various shapes and in particular, includes sheet-type carbon in a certain content, when the sulfur-carbon composite is applied as a positive electrode active material of a lithium secondary battery, the performance of the lithium secondary battery may be improved by preventing the leaching of sulfur and improving the reaction rate at the positive electrode.
