Ionic conductivities of solid polymer electrolytes: The effect of pressure

A molecular thermodynamic model based on the theory of melting point depres sion, the Adam-Gibbs configurational entropy model, and the lattice fluid m odel was developed to interpret the ionic conductivities of solid polymer e lectrolytes with various pressures. Quantitative descriptions according to the proposed model are in good agreement with the experimental data for the given systems. Our results show that an eutectic point moves toward a high er T-m and lower weight fraction of salt, and the ionic conductivity signif icantly decreases with pressure.
