Abstract

To observe whether pressure acting on the liquid state of a fast ion conducting vitreous solid electrolyte has a very different effect from pressure acting on the fixed structure vitreous state, measurements have been performed on (AgI)40(AgPO3)60 over a range of pressures and temperatures. Below Tg, conductivity decreases according to classic transition state theory expressions with volume of activation close to the mobile ion volume. Pressure applied near and above Tg has only a slightly different effect than the same pressure applied well below Tg below, in contrast to the pressure effect on viscosity above Tg. An explanation links weak pressure effects to previously known weak quenching (fictive temperature) effects, through the high decoupling index.
