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.
