Abstract
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.
Claims22
A method for embedding sulfur into conductive carbon, the method comprising:
- dissolving elemental sulfur in liquid ammonia to form a sulfur-ammonia solution;
- soaking conductive carbon in the sulfur-ammonia solution to embed the conductive carbon with at least a portion of the dissolved sulfur;
- and
- recovering the sulfur-embedded conductive carbon.
