ResumoThe electrical properties of Li3NLiILiOH (1:2:x molar ratio) compounds are investigated. These quasi-ternary compounds have a cubic crystal structure similar to Li5NI2. The Li3NLiILiOH (1:2:0.77) compound has a conductivity of 0.95 × 10−1 (S/m at 25°C with an activation enthalpy of 24.6 (kJ/mol). All the compounds investigated are predominantly ionic conductors. The electronic transference number is smaller than 10−5 and the decomposition voltage of these compounds is about 1.6V at 25°C.
