SAXS/DSC/WAXD Study of Zn2+-ion Conducting Polymer Electrolyte

Electrolytes are nano-structured materials that are very attractive for batteries or other types of electronic devices. (PEO)8ZnCl2 polymer electrolytes were studied by small-angle X-ray scattering (SAXS) simultaneously recorded with differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD) at the synchrotron ELETTRA. It was shown by previous impedance spectroscopy (IS) that the room temperature conductivity of polymer electrolyte increased two times above 65°C. The SAXS/DSC measurements yielded insight into the temperature-dependent changes of the grains of the electrolyte. The crystal structure of the nanosize grains was revealed by the simultaneous WAXD measurements.
