Zusammenfassung:The present disclosure relates to a carbon composite for use in a cathode of a lithium-sulfur battery and a method for preparing the same. The carbon composite material includes: a porous carbon support; a catalyst containing a transition metal; and a carbon layer coated on at least a portion of a surface of the catalyst, where the transition metal comprises at least one element of cobalt (Co) and iron (Fe), and where the carbon layer comprises a nitrogen (N)-containing carbon compound.
