(57) [Problem] To provide a lithium-sulfur battery exhibiting high capacity and excellent high rate characteristics. SOLUTION: 60 wt% of elemental sulfur, 20 wt% of carbon black and 20 wt% of polyvinylpyrrolidone are mixed with a dimethylformamide solvent, coated on a carbon-coated Al current collector, and vacuum dried at 60 ° C. to produce a positive electrode plate. I do. Lithium electrode as a negative electrode, and 1M LiSO 3 CF 3 as a mixed electrolyte dissolved in dimethoxyethane / sulfolane / 1,3-dioxolane (1,3-dioxolane) (3: 1: 1 by volume) Is used to manufacture a lithium-sulfur battery in a usual manner. |
