Ion conducting polymer electrolyte films having high salt concentrations have been studied. The system studied is PEO∶NH4I, dispersed with α-Al2O3. Mechanically stable films with NH 4 + /EO ratio ≥0.13 have been obtained by dispersal of Al2O3. The films have been characterized using various techniques such as X-ray diffraction (XRD), differential thermal analysis (DTA), polarization and complex impedance spectroscopy. Intercorrelation between polymer matrix crystallite size, conductivity, and α-Al2O3 particle size is established.
