In this work, a solid state electrolyte composed of Li2C03 and Lil was successfully prepared using mechanical milling method followed by low sintering process.

From the measurement, the xLi2C03-yLiI (x = 80, y = 20) solid electrolyte displayed the highest electrical conductivity of 1.03x10-3 Scm-1 at room temperature.

A noteworthy increase of ionic conductivity up to 1.75x10-3 Scm- 1 was observed at room temperature with the presence of ZnO filler. The enhancement in electrical conductivity could be due to the interaction between ionic species and Lewis acid-base group on the filler surface and hence, improve the dissociation rate of ions in solid. Incorporation of 9 wt.% Mn02 has successfully amplified the overall conductivity of the sample (3.87x10-1 Scm-1) by increasing the available charge carrier concentration and newly established percolation network for the migration of ions.
