Abstract:
Disclosed are a cathode for metal-sulfur batteries which includes a cathode active material layer, which contains nitrogen-doped carbon, and a protective layer and a method of manufacturing the same. The cathode for lithium-sulfur batteries according to the present invention includes a cathode active material layer including a sulfur-containing material, a binder, and a nitrogen-doped carbon material; and a protective layer that is disposed on the cathode active material layer and is composed of a nitrogen-doped carbon material, wherein the nitrogen-doped carbon material of the cathode active material layer has a form wherein spherical particles and linear structures are mixed and the nitrogen-doped carbon material of the protective layer has a linear structure.
