CERIA-CARBON-SURFUR COMPLEX, MANUFACTURING METHOD THEREOF, POSITIVE ELECTRODE AND LITHIUM-SULFUR BATTERY COMPRISING THE SAME

摘要

The present invention is ceria (CeO _{2) Ceria-carbon (CeO 2} -C) composite in which the cylindrical carbon material to which the particles are bonded to the surface are entangled and interconnected in three dimensions; And sulfur introduced into at least a portion of the outer surface and the interior of the ceria-carbon composite; a ceria-carbon-sulfur (CeO ₂ -CS) composite, a method for preparing the same, and a lithium-sulfur battery positive electrode and lithium- It relates to a sulfur battery.
