Modeling and simulation of Li-ion conduction in poly(ethylene oxide)
TL;DR: This model and simulation of Li^+ ion conduction in a single PEO molecule predicts the PEO conductivity as a function of the stretching, the salt concentration and the temperature, and the computed enhancement of the ionic conductivity in the stretch direction is in good agreement with experimental results.

Conductivity, charge transfer and transport number—an ac-investigation of the polymer electrolyte LiSCN-poly(ethyleneoxide)
TL;DR: In this paper, a series of impedance measurements in the frequency range 10−4−2 × 105 Hz and in the temperature range 20-170°C is reported for the cell: Li-metal/LiSCN [dissolved in poly (ethyleneoxide)]/Li-metal On the basis of the measurements a whole range of electrical properties such as the conductivity, the charge transfer resistance, the transport number for the Li+-ion, the double layer capacity and the dielectric constant were determined for the polymer complex.
