Characterization of nanocomposite polyvinyl alcohol/cellulose acetate blend gel polymer electrolytes for supercapacitor application

High ionic conductivity polymer electrolyte has been introduced to replace the liquid electrolyte used in commercial energy storage devices as they have a tendency in leakage. However, the high degree of crystallinity in polymer electrolyte limits further enhancement of ionic conductivity. In this w...

The trend of the FTIR spectrum in the hydroxyl band showed that the lowered shifting wavenumber indicates a decreased crystalline phase with increasing TiO2 concentration. The highest conductivity of (3.30 ± 0.15) Å~ 10−4 S cm−1 at room temperature was obtained with addition of 8 wt% of TiO2.
