Abstract: The present disclosure relates to a sulfur-carbon composite and a preparing method thereof, and more particularly, to a sulfur-carbon composite having an aggregated structure by performing a pressure heat treatment on a mixture of a carbonaceous conductive material and a sulfur-containing amorphous carbon material and carbonizing the same, and a preparing method thereof.According to the present disclosure, the sulfur and the amorphous carbon material are present in the sulfur-carbon composite including the sulfur-containing amorphous carbon material and the carbonaceous conductive material by being aggregated through the pressure heat treatment and the carbonization process. As a carbon component in a carbon matrix of the amorphous carbon material and the sulfur are chemically bonded to each other, the sulfur may be prevented from leaking from the composite.
