| description | A method for making a sulfur based cathode composite material is disclosed. Polyacrylonitrile and elemental sulfur are dissolved together in a first solvent to form a first solution. An additive is added to the first solution to mix with the polyacrylonitrile and the elemental sulfur. The additive is at least one of metal and metal sulfide. An environment in which the polyacrylonitrile and the elemental sulfur are located in is changed to reduce a solubility of the polyacrylonitrile and the elemental sulfur in a changed environment to simultaneously precipitate the polyacrylonitrile and the elemental sulfur, thereby forming a precipitate having the additive. The precipitate is heated to chemically react the polyacrylonitrile with the elemental sulfur. |
