Synthesizing glass electrolytes with modified ionic conductivity by incorporating Li 2 O for enhanced secondary battery safety is ever-demanding. Electrolytes based on zinc-tellurite glasses with chemical composition (85- x )TeO 2 × x Li 2 O×15ZnO, where x = 0, 5, 10, 15 mol% are prepared using melt quenching method. The temperatures, frequency and Li 2 O concentrations dependent modifications of structural features, thermal stability, and ionic conductivity are determined. Amorphous nature of electrolytes is verified from X-ray diffraction patterns. Incorporation of Li 2 O in the electrolytes is found to decrease the glass transtition temperature from 318.41 to 280.63 °C leading to their thermal stability enhancement. Alternating current impedance measurement revealed that the ionic conductivity of the electrolytes is significantly influenced by the temperature and concentration of Li 2 O and not by the frequency of AC voltage. The glass electrolyte containing 5 mol% of Li 2 O exhibited good performance with the ion conductivity of 1.72´10 -2 S cm -1 and activation energy of 3.85´10 -1 eV. These improvements in the conductivity and activation energy are attributed to the alteration in ions vibration and breakage of covalent bonds. This modification allowed the ions to move through un-perfect non-bridging oxygen under the influence of an external electric field (applied voltage) with enhanced mobility. The present glass electrolyte is very promising for secondary Li-ion battery fabrication.
