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

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