This paper describes the preparation and characterization of poly(ethylene oxide) (PEO)-lithium his(perfluoroethylenesulfonyl)imide (LiBETI), LiN(SO2CF2CF3)2polymer electrolytes. The structural properties of P(EO)nLiBETI 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.
