Abstract
This paper describes the preparation and characterization of poly(ethylene oxide) (PEO)-lithium bis(perfluoroethylenesulfonyl)imide (LiBETI), LiN (SO2CF2CF3)2(SO2CF2CF3)2 polymer electrolytes. The structural properties of P(EO)nP(EO)n LiBETI electrolyte tapes, investigated using X-ray diffraction (XRD) and differential scanning calorimetry (DSC), are correlated with their ionic conductivities. PEO-LiBETI complexes were found to have very high ionic conductivities due to their amorphous structure. © 2001 The Electrochemical Society. All rights reserved.Keywords
