Abstract
Provided are electrode active materials that include a metal oxide or oxynitride with a porous structure that when loaded with sulfur serve as electrochemically superior cathode active materials. The metal nitride or metal oxynitride structures are optionally used on their own, are coated with another material, or itself coats another porous structure such as a porous carbon structure that allows for excellent retention of both sulfur and polysulfides, are conductive themselves, and show long term stability and excellent cycle life.
