![]() ![]() This article presents a comparative analysis of three distinct zirconia-inserted polyvinyl alcohol (PVA) polymer matrices. The highest conducting electrolyte has been incorporated into a primary battery to showcase its potential application in energy storage devices. The sample complexed with 20 wt.% of NaNO3 revealed the highest room temperature conductivity of 1.75�10�4 Scm�1, among all other samples with suitable mechanical strength to be incorporated into energy storage devices. Nyquist plot fitting has been performed to evaluate the transport properties hence carrier concentration influences ionic conductivity. The Tg of the samples have been found to increase with salt concentration indicating transient cross-links. Fourier-transform infrared analysis confirmed the complexation of the salt via coordinate bond/hydrogen bond with –OH and –CH groups of the polymer blend. X-ray diffraction showed an increase in the amorphous phase of the polymer blend with increasing salt concentration up to samples containing 20 wt.% of NaNO3 supported by the scanning electron microscope studies. ![]() In this work, the effect of NaNO3 salt concentration (0, 5, 10, 15, 20, 25, and 30 wt.%) on the structural, electrical, and mechanical properties of Nacarboxymethyl cellulose/polyvinyl alcohol polyblend electrolyte films has been studied. ![]()
