Abstract
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 °C with excellent performance. This study demonstrates a new type of high-performance metal–sulfur battery that is ideal for grid-scale energy-storage applications.Keywords
