SULPHUR CATHODES, SULPHUR CATHODE MATERIALS, AND APPARATUS AND METHODS FOR MAKING SAME

A method for embedding sulphur into conductive carbon is provided. Elemental sulphur is dissolved in liquid ammonia to form a sulphur-ammonia solution. Conductive carbon is soaked in the sulphur-ammonia solution to embed the conductive carbon with the dissolved sulphur. The liquid ammonia in the sulphur-ammonia solution can be removed as gaseous ammonia to yield sulphur-embedded conductive carbon. The sulphur-embedded conductive carbon can be used to manufacture sulphur cathodes. Such sulphur cathodes and batteries incorporating such sulphur cathodes are provided.
