The present invention relates to a polymer-sulfur copolymer, a method for producing the same, and a lithium-sulfur battery including the same. In the polymer-sulfur copolymer according to the present invention, the carrier is polymerized and there is no fear of elution of the carrier. Since sulfur is covalently bonded to the polymer and uniformly distributed in the copolymer, the polysulfide when used as a cathode active material of lithium- The dissolution problem can be improved. In addition, since it has a high sulfur impregnation amount, it is possible to realize a high capacity battery. |
