SAXS/DSC Study of Polymer Electrolyte for Zn Rechargeable Nanostructured Galvanic Cells

(PEO)8ZnCl2 polymer electrolytes and nano-composites were prepared using PEO g-irradiated to selected dose of 309 KGy and TiO2 nanograins. The influence of added nanosize TiO2 grains to polymer electrolytes and the effect of g-radiation from a Co-60 source were studied by small-angle X-ray scattering (SAXS) simultaneously recorded with differential scanning calorimetry (DSC) at synchrotron ELETTRA. Impedance spectroscopy (IS) was also performed. Above-mentioned treatments largely enhanced the conductivity of polymer electrolyte. Room temperature conductivity increase up to two orders of magnitude was achieved. Addition of nanograins increased conductivity more than can be ascribed to crystallinity possibly because of interactions of anion with nanograins.
