✦ Synopsis

EXAFS studies on polymer electrolyte systems have provided a unique means of addressing local structure-conductivity relationships. Most polymer electrolytes are anion as well as cation conductors, but it is often desirable to enhance the cation contribution. Conductivity can be enhanced by plasticizers or alternatively by incorporation of two inorganic salts, rather than one, in the polymer matrix. Results are described for the following: (i) PEO,,: (0.5 ZnBr,), (0.5 CaBr,); (ii) PEO,,: (0.5 ZnI,), (0.5 CaI,); (iii) (PEO,: ZnCl,), (0.7 ethylene carbonate); (iv) PEO,,: (0.5 ZnBr,), (0.5 ZnI,).
