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 K_XWO₃ as electrodes has been measured and compared.
