Abstract

The present work is based on the influence of addition of BiNiFeO3 nanoparticles on the charge transport mechanism of PVA-NH4CH3COOpolymer gel electrolyte. Pure BiNiFeO3 nanoparticles and the gel membranes are synthesized by sol-gel and solution cast methods respectively. XRD spectrum of pure BiNiFeO3 confirms the nanometric dimension. FTIR studies reveals interaction and shifting in characteristics peaks of constituents. The impedance analysis shows at 0.4 wt% BiNiFeO3 embedded with electrolyte has higher bulk conductivity. Cyclic voltammetry analysis on the membranes shows better electrochemical stability i.e. ±4.68 V and confirms the availability of H+ ion (proton) in the system suggested proton-conducting batteries application.
