摘要：
A molecular thermodynamic model based on the Adam-Gibbs configurational entropy model and the modified double lattice model with the free volume effect is applied to interpret ionic conductivities of solid polymer electrolytes with various pressures. Quantitative descriptions according to the proposed model are in good agreement with experimental data for the given systems. Our results show that an eutectic point moves toward higher T-m and lower weight fraction of salt, and the ionic conductivity significantly decreases with increasing system pressure.
