Abstract
Gel electrolyte films were prepared by a redox initiated copolymerizat ion of oligo(ethylene glycol)(23) dimethacrylate and acrylonitrile in the presence of oligo(ethylene glycol)(11) dimethyl ether as a plastic izer and LiCF3SO3. The influence of the polar comonomer acrylonitrile on the conductivity and the cationic transference number was investiga ted. The materials show conductivities between 10(-4) and 10(-5) S cm and transference numbers in the range of 0.5 at room temperature. Puls ed field gradient-NMR (PFG-NMR) measurements were carried out to deter mine the diffusion coefficients of the plasticizer by(1)H-NMR and of L iCF3SO3 by F-19-NMR.
