Synthesis and electrical properties of Ag16I12P2O7

Abstract

Superionic solid electrolyte Ag16I12P2O7 was prepared using solid state synthesis. The ionic conductivity of this compound was studied by the complex impedance spectroscopy method in a wide temperature range. It is shown that Ag16I12P2O7 is characterized by a high ionic conductivity at room temperature, comparable to the conductivity of liquid electrolytes.
