CATHODE ACTIVE MATERIAL FOR LITHIUM-SULFUR BATTERY, METHOD OF PREPARING THE SAME AND LITHIUM-SULFUR BATTERY INCLUDING THE SAME

摘要

The present invention relates to a positive electrode active material for a lithium-sulfur battery, a method for manufacturing the same, and a lithium-sulfur battery including the same. The positive electrode active material for a lithium-sulfur battery comprises a porous graphene sheet; a carbon layer formed on internal pores and at least one part of the surface of the porous graphene sheet; and sulfur placed on the internal pores and at least one part of the surface of the porous graphene sheet including the carbon layer.
