Abstract:
A ceria-carbon-sulfur (CeO2—C—S) composite including a ceria-carbon (CeO2—C) composite in which cylindrical carbon materials having ceria (CeO2) particles bonded to surfaces thereof are entangled and interconnected to each other in three dimensions; and sulfur introduced into at least a portion of an outer surface and an inside of the ceria-carbon composite, a method for preparing the same, and positive electrode for a lithium-sulfur battery and a lithium-sulfur battery including the same.
