Description
Summary:A micro‐Raman study of triblock polyether/LiCF3SO3 polymeric electrolytes was carried out over a wide range of salt concentrations at room temperature. The different associated species were evidenced by means of a lineshape analysis of the bands related to the symmetric stretching mode ν1 of the SO3− termination and to the C–S vibration of the CF3SO3− anion. The Raman results reveal that the appearance of new associated species coincides with the saturation of prior species. Copyright © 2001 John Wiley & Sons, Ltd.
