چکیده    Inorganic electrolyte consisting of li2co3 and lii with the incorporation of mno2 as fillers was prepared by a mechanical milling technique. the effects of ceramic filler concentration on the electrolyte host system were investigated by deploying electrical impedance spectroscopy,eis measurement at a temperature range of 298-373k. it was revealed that incorporating 9 wt. % mno2 filler in li2co3/lii electrolyte significantly enhanced the electrical conductivity from 4x10-3 s/cm up to 8x10-3 s/cm. nano-particle inorganic oxides have been found to act as ions dissociation enhancer in solid electrolytes. dielectric analysis was performed to investigate the ions migration process in solid electrolyte. the dielectric study showed that the ionic conductivity of the electrolyte was observed to increase as a function of temperature,suggesting that the system is thermally assisted. the plots of electrical conductivity,as a function of temperature have been varied from 298 – 373k and were found to obey the arrhenius law. © 2015,penerbit utm press. all rights reserved.
