The reinforcement of the ionic conductivity in a lithium-vanadium-molybdenum tellurite glass is possible by modified with zinc oxide {0.7 [x ZnO (1−x) Li2O] 0.3 [0.5 V2O5. 0.5 MoO3]. 2TeO2}. Structural features induced by zinc cation on the glassy matrix have a positive effect on the electrical behavior of the modified glass. The electrical response of the Zn/Li tellurite glass studied in the present work gives evidence that its ionic conductivity is improved due to the incorporation of small quantities of ZnO suggesting a potential solid ionic electrolyte useful in solid electrochemical devices.
•Conductivity increase due to the ZnO incorporation in a Li-V-Mo tellurite glassy.•Li-conductivity pathway is not disturbed for the presence of the zinc cations.•A mix of Li2O and ZnO does not give evidence of MMIE in a Li-V-Mo tellurite glassy.
