Abstract

Here, we develop an anion-dominated cosolvent electrolyte (CSE) composed of 1.5 M KFSI in TFP/DEE. The electrolyte is fire-resistant and compatible with potassium metal, a graphite anode, and a K_0.5MnO₂ cathode. The K|CSE|K_0.5MnO₂ cells operate steadily up to 4.1 V for 2500 cycles at 1000 mA g^-1.
