title: High-Conductivity Solid Electrolytes: MAg4I5.
abstract: The solid electrolytes MAg(4)I(5), where M may be potassium, rubidium, or ammonium, have an ionic conductivity of 0.2 (ohm cm)(-1) at 20 degrees C. Although pure CsAg(4)I(5) does not form, partial substitution of cesium into the M position was obtained. The high-conducting phases of KAg(4)I(5) and RbAg(4)I(5) may be quenched to low temperatures, where they transform to resistive phases at -136 degrees and -155 degrees C, respectively.
