Abstract

Because of the procedures associated with the deconvolution of the data present in an EXAFS spectrum, the experimental XAFS spectra also include both the edge and XANES regions. It is possible to obtain additional structural and chemical information from the data associated with these regions of the XAFS spectrum and in this work we have re-examined the XAFS spectra for a series of polymer electrolytes. These spectra were originally recorded for EXAFS analysis. The XANES spectra for PEOn:CaBr2 electrolytes confirm that the behaviour of calcium polymer electrolytes appears to be very different from that of other divalent based electrolytes. We have also examined the edge features for PEO8:NiBr2 samples which were subject to different thermal histories and evidence for phase separation is presented.
