Study on PVDF-HFP Based Nanocomposite Polymer Electrolytes for Energy Storage Devices Dispersed with Various Nano-Fillers | Chapter 01 | Research Trends and Challenges in Physical Science Vol. 7

 Various compositions of nanocomposite polymer electrolyte (NCPE) films were successfully synthesised using the solution casting method, including Polyvinylideneflouride-co-hexafluoropropylene (PVDF-HFP) as a host, Magnesium chloride (MgCl2) as an ionic salt, and various concentrations of nanosized ceramic fillers -TiO2, MgO, ZnO, and Al2 The effect of various ceramic filler dispersion in SPE on ionic conductivity of SPE has been addressed. At room temperature, the best bulk conductivity () for optimum conducting composition (OCC) of solid polymer electrolyte is 4.69x10-7 S/cm-phase-Ist. Further, with the addition of filler-phase IInd, conductivity rose and reached a maximum for NCPE composition, i.e. PVDF-HFP: MgCl2: ZnO (70:30:3) of 1.25x10-5 S/cm, and from temperature dependency investigation, we obtained a maximum for OCC of NCPE at 110 0C of 1.24x10-4 S/cm. Impedance All samples' electrical characteristics were measured using spectroscopy in the frequency range 42Hz-5MHz and temperature range 30-1100C. X-ray Diffraction (XRD) was employed to characterise the structural properties of these NCPE films. Wagner's dc polarisation approach yielded an ion transport number of 0.99 for the OCC of the NCPE system.
