A micro‐Raman study of triblock polyether/LiCF 3 SO 3 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 ν 1 of the SO 3 − termination and to the C–S vibration of the CF 3 SO 3 − 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.
