Ionic Conductivity and Dielectric Constant of a Solid Polymer Electrolyte Containing Salts Litf2 and Mgtf2

Abstract

            In this work, two samples of a solid polymer electrolyte have been prepared from a 20% concentrated solution of LiTf₂ and MgTf₂ salts.In this case, we obtained two different samples using as a polymer: PMMA as an active material LiTf₂, MgTf₂, and as a solvent ethylene carbonate and tetrahydroflun (THF).The technology of sample preparation and the parameters of active, reactive impedance, conductivity, dielectric constant have been determined. Compared to each other, the ionic conductivity of LiTf₂ was , while that of MgTf₂ was .
