SULFUR-CARBON COMPOSITE COMPRISING MICRO-POROUS CARBON NANOSHEETS FOR LITHIUM-SULFUR BATTERIES AND PROCESS FOR PREPARING THE SAME

摘要

A sulfur-carbon composite includes micro-porous carbon nanosheets and sulfur. The sulfur is loaded into the micropores of the micro-porous carbon nanosheets. The sulfur-carbon composite can be included in an electrode material. The sulfur-carbon composite can be included in a lithium-sulfur battery. A process for preparing the sulfur-carbon composite includes carbonization-activation of carbonaceous precursor, purification, and loading of sulfur into micro-porous carbon nanosheets.
