The Need to Reconsider Traditional Free Volume Theory for Polymer Electrolytes

Abstract

Pressure-temperature-volume (PVT) data have been obtained for poly(propylene glycol) of molecular weight 1025 containing LiCF3SO3 in the mole ratio 20:1. The PVT data were used to calculate the specific volumes, V/V(sub P = 0, TAU = 296 K), associated with the pressures and temperatures for previously published variable temperature, high-pressure electrical conductivity data. It is found that the electrical conductivity depends strongly on temperature at a constant volume. Consequently, traditional free volume theory is not consistent with the data. Finally, it is shown that the features of the electrical conductivity data can be accounted for by a recently developed generalized Vogel theory.
