Solid-state inorganic electrolytes for next generation potassium batteries

Abstract

Abstract Necessary diversification of battery chemistry and related cell design call for investigation of more exotic materials and configurations, such as solid-state potassium batteries. In the core of their development lies the necessity of discovering new and electrochemically more efficient inorganic solid-state electrolytes. This review focuses on suitable chemical structures, their fundamental properties and status of the materials synthesis, related electrochemical performance, contemporary characterization techniques and modeling efforts for inorganic solid-state potassium electrolytes.
