A lithium-sulfur battery includes a positive electrode having at least one positive activenmaterial selected from the group consisting of an elemental sulfur, Li 2 S n (n≥1), Li 2 S n (n≥1)ndissolved in catholytes, an organosulfur compound, and a carbon-sulfur polymer ((C 2 S x ) n : x =n2.5∼50, n ≥2), an electrolyte having salts of an organic cation, and a negative electrode havingna negative active material selected from the group consisting of a material capable of reversiblynintercalating/deintercalating lithium ions, a material capable of reversibly forming a lithium-containingncompound by a reaction with lithium ions, a lithium metal, and a lithium alloy. |
