Conductividad iónica en nuevos compositos (PEO)10(CF3COONa)-X% Al2O3

To increase the ionic conductivity of solid polymer electrolyte, (PEO)10 CF3 COONa, we formed new composites by adding alumina particles as a filler. We prepared these composites by dissolving them in a liquid solvent, and characterized them through impedance spectroscopy (IS), using a Pt/electrolyt...
