Ionic Conductivity and Structure of Double Chloride Li2ZnCl4 in the LiCl–ZnCl2 System

Abstract The phase diagram of the LiCl–ZnCl2 system was determined. The system contained one intermediate compound, Li2ZnCl4; it transformed from the normal spinel to the olivine structure at 215 °C. Electrical conductivity measurements showed a high ionic conductivity of 2.0 × 10−4 S cm−1 280 °C.
