In this context, nanocomposite polymer electrolytes are attracting scientific and technological importance due to their potential applications in many areas such as solid state batteries, fuel cells, super capacitors and electrochromic devices etc. In general, nanocomposite polymer electrolytes are plasticized materials whose structure and properties can be tailored for specific needs namely in electrochemical devices like in solid state ionic batteries. An attempt are made to develop and characterize the effect of salt in the improvement of ion transport property of polyethylene oxide (PEO)-based polymer electrolytes subsequent to dispersal of nanosized Zn-ferrite as a filler particles. The nanocomposite polymer electrolyte system [(1-x) PEO: xNH4SCN]:1wt% Zn-ferrite films are prepared by solution cast technique. Zn-ferrite nano powder is synthesized through well known sol-gel process at ambient temperature. The structural and morphological behaviors of NCPEs are studied with the help of XRD and OM measurements. Electrical conductivity measurements of nanocomposite polymer electrolytes samples are carried out using impedance spectroscopic technique. Dielectric relaxation studies are extracted by impedance data to assess ion conduction mechanism in electrolyte system. Electrochemical stability of NCPE is studied under the CV measurement and show better electrochemical response upon dispersal of Zn-ferrite. To check the utility of as synthesized NCPEs in electrochemical devices, solid state rechargeable proton conducting batteries are fabricated for optimally conducting electrolytes systems. The Solid State battery of sample containing 1wt% Zn ferrite in [93PEO-7NH4SCN]: polymer electrolyte gives better response of OCV (1.46V) and having energy density = 403 µWh/Kg.
