Development of Magnisio Ferrite Doped Polymer Electrolyte System for Battery Application

Ion transport property of [93PEO-7NH4SCN]: Mg-Zn Magnisio ferrite electrolyte system have been investigated here with the aim of developing a high performance solid state battery. Wet chemistry route has been adopted to obtain this electrolyte. XRD patterns (Debye-Scherer a Williamson Hall plot calculations) ascertain formation of nanocomposite system. Different ion transport parameters like bulk conductivity, dielectric loss, tangent loss and modulus spectra were studied with the aid of impedance spectroscopic data. Optimum d.c. conductivity has been observed for [93PEO-7NH4SCN]: 1wt% Mg-Zn ferrite system (9.0x10-5 S/cm) and a.c. conductivity of nanocomposite polymer electrolytes seems to follow the universal power law. Battery performance of this electrolyte was tested and OCV of best system is found to be 1.57 Volt.
