Paper Abstract

Different anhydrous potassium ion conducting polymer electrolytes have been studied : (POE)nKTFSI (trifluorosulfonimide), plasticized (POE)nKTFSI, (PEM)nKTFSI and (POE-Acetal)nKTFSI. DSC and conductivity measurements have been used to characterize these electrolytes. Several solutions to avoid cristallization have been examined. The best conductivity has been obtained with (POE-Acetal)nKTFSI. This electrolyte exhibits good transmission in the VIS-IR region. The response time of cells using these electrolytes and Prussian blue and KXWO3 as electrodes has been measured and compared.
