Abstract
A sulfur-carbon composite including porous carbon material, and sulfur, wherein at least a portion of an inside and a surface of the porous carbon material coated with the sulfur, the sulfur-carbon composite has a pore volume of 0.180 cm3/g to 0.300 cm3/g, and the sulfur-carbon composite has an average pore size of 40.0 nm to 70.0 nm, and a method of manufacturing the same. Also, a method of manufacturing a sulfur-carbon composite, which includes (a) mixing a porous carbon material with sulfur particles, wherein the sulfur particles have a particle size of 1 nm to 1 μm using a Henschel mixer; and (b) drying the resulting mixture of (a).
