Abstract

1H, 7Li and 19F NMR relaxation times have been measured in the amorphous phase of the polymer solid ionic conductor: PEO (LiBF4)0.125. Our results suggest that cation motion is controlled by segmental motions of the polymer chain while the anion have additional mobility associated with (BF4) - rotation.
