SYNTHESIS AND ELECTROCHEMICAL CHARACTERIZATION OF A NEW FAMILY OF LITHIUM-SALTS

This paper deals with the chemical and electrochemical characterizatio n of a novel lithium salt which has a bulky delocalized anion. This sa lt has been synthesized with a good overall yield by reacting (CF3SO2) 2CHNa with an acid chloride C6H5COCl. The crystallinity of high molecu lar weight host polymer POE is notably reduced by dissolution of the s alt and, at room temperature, some complexes provide the best conducti vities known up to now. Furthermore a microvoltammetry study has shown the wide electrochemical window of this salt.
