A potassium-sulfur battery using K+ conducting beta-alumina as the electrolyte to separate a molten potassium metal anode and a sulfur cathode is presented. The results indicate that the battery can operate at as low as 150 degrees C with excellent performance. This study demon strates a new type of high-performance metal-sulfur battery that is ideal for grid-scale energy-storage applications.
