Ionic Conductivity of Lithium Based Electrolytes in the LiI-Li 2 O-MoO 2 -V 2 O 5 (LMV) Quaternary Glass System

Glass electrolytes of the LMV system are being prepared in various compositions by the melt quench technique. The mixture is heated to very high temperature to obtain a homogeneous melt which is quenched in liquid nitrogen. The Li+ ions are provided by dopant LiI and the Li2O acts as a modifier of the glass network formed by MoO2 and V2O5. The samples are characterized by XRD, IR, and Electrochemical Impedance technique. The ionic conductivity is calculated from the bulk resistance obtained from the impedance measurements. The impedance is measured at room temperature as well as various temperatures. The heating and cooling effect on impedance is measured from room temperature till 100°C. The conductivity measured is in the range of 10-5 Scm-1. The IR showed the cluster formation and the temperature variation studies of impedance provided an insight into the behavior of these glasses at different temperatures.
