✦ Synopsis
Different anhydrous potassium ion conducting polymer electrolytes have been studied: (POE)nKTFSI (trifluorosulfonimide), plasticized (POE),KTFSI, (PEM),KTFSI and (POEacetal),KTFSl. DSC and conductivity measurements have been used to characterize these electrolytes. Several solutions to avoid crystallization have been examined. The best conductivity has been obtained with (POE-acetal)nKTFSI. This electrolyte exhibits good transmission in the VIS-IR region. The time response of cells using these electrolytes and Prussian blue and KxWO 3 as electrodes has been measured and compared. The influence of H20 on cycling is also presented and discussed.
