ABSTRACT:

The electrical conductivity for the glass system (AgPO3)1-x(AgI)x, where 0 ??? 0.5, is determined by the impedance method in the frequency range 100Hz-1MHz and the temperature range from room temperature to glass transition temperature.The impedance plot appeared on the complex plane as semicircles passing through origin The temperature dependence of conductivity grows linearly reaching a value of 0.6?10-2 (W-1cm-1) for a composition x=0.5 which is identified as a ?fast-ionic? conductor. Variations of e' and e" with frequency and temperature are found , which corresponds to an interfacial process. The dielectric constant is found to be increasing with increase AgI content which is due to the fact that the mobile ion concentration increases, which leads to the increasing of conductivity. The composition The charge-discharge processes of Ag/SE/Ag2S battery using AgPO3 -AgI superionic glasses based solid electrolyte is studied.
