The present invention relates to a polymer-sulfur copolymer, a method for preparing the same, and a lithium-sulfur battery including the same. The polymer-sulfur copolymer according to the present invention has no fear of carrier elution because the carrier is polymerized, and since sulfur is covalently bonded to the polymer and evenly distributed in the copolymer to a certain size, polysulfide when used as a cathode active material of a lithium-sulfur battery Dissolution problems can be improved. In addition, it has a high sulfur impregnation amount, it is possible to implement a high capacity battery. |
