Effect of ZrO2 Nanofiller on Ionic Conductivity Studies of PVP-CH3COONa.3H2O Polymer Electrolyte Films.

Zirconium oxide (ZrO2) doped solid polymer electrolytes have been prepared with different compositions of PVP-CH3COONa.3H2O by solution cast technique. AC ionic conductivity measurements were performed on the prepared films in the frequency ranging from 400 Hz to 50000 KHz. The ionic conductivity of the film was found to be maximum (2.42x10−3 S/cm) for the prepared sample 60PVP:40CH3COONa.3H2O:ZrO2 (1 wt%) at room temperature. The majority transfer of ions and electrons in the solid polymer electrolytes can be calculated by transport properties. Finally an electrochemical cell was fabricated and the discharge characteristics were studied. [ABSTRACT FROM AUTHOR]
