Abstract
Provided herein is a cathode for lithium-sulfur battery. The cathode for lithium-sulfur battery has a structure for improved in charge/discharge efficiency, charge capacity, and life span. In particular, in the cathode structure, an active material is inserted into a porous carbon structure and a surface of the porous carbon structure is densely coated with the conducting material thereby maximizing the contents of an active material and a conducting material in the cathode without a current collector.
