Ionic Conductivity of K-ion Glassy Solid Electrolytes of KS-PS-KOTf System.

Ternary glassy electrolytes containing KS as a glass modifier and PS as a network former are synthesized by introducing a new type of complex and asymmetric salt, potassium triflate (KOTf), to obtain unprecedented K ion conductivity at ambient temperature. The glasses are synthesized using a conventional quenching technique at a low temperature. In general, alkali ionic glassy electrolytes of ternary systems, specifically for Li and Na ion conductivity, have been studied with the addition of halide salts or oxysalts such as MSO, MSiO, MPO (M = Li or Na), etc.
