The invention provides a lithium-sulfur battery positive copolymer sulfur material. The lithium-sulfur battery positive copolymer sulfur material is prepared through steps as follows, (1), sublimed sulfur powder and organic polymerization agent are collected to obtain uniform mixture through grinding, and the organic polymerization agent is nitrile organic substance; (2), the uniform mixture of the sublimed sulfur and the organic polymerization agent is sealed in a container under the high temperature condition and is insulated and stirred; and (3), the copolymerized sulfur obtained in the step (2) is pulverized to obtain positive electrode copolymerized sulfur particles. The invention further provides a lithium-sulfur battery made from the lithium-sulfur battery positive copolymer sulfurmaterial. The lithium-sulfur battery positive copolymer sulfur material is advantaged in that preparation requirements can be met through simple heating equipment, and the preparation process has characteristics of convenient operation and simple process. The preparation method is advantaged in that chemical bonding between the organic matter and the sulfur is produced through bond opening reaction of nitrile compounds'unique carbon-nitrogen triple bond and the 8-membered ring structure of the sublimated sulfur at the high temperature, and the polymeric sulfur copolymer can be formed.
