In this podcast episode, together with our guest, Dr. Holger Althues (IWS Fraunhofer Institute), we shed light on the element sulfur as an electrode material for different battery types. More specifically, we talk about the extraction, processing and effect of sulfur in the battery as well as the different battery types. This new type of batteries is considered one of the most promising next generation technologies. They have not yet arrived on the market, as there are still some challenges to overcome. Sodium-sulfur batteries are further ahead, and are already commercially available. They differ greatly in the way they work: Sodium-sulfur thermal batteries, for example, function at an operating temperature of more than 200 °C and are already in use in Japan.
