Temperature dependence of active and reactive impedances of PMMA-EC-LiTf / MgTf2 solid polymer electrolytes

Abstract

In this work, PMMA-EC-LiTf, PMMA-EC-MgTf₂ samples were prepared at a concentration of 20%. Using Nyquist coordinates, results were obtained for active and reactive impedances at temperatures from 243K to 283 K  and at temperatures from 303 K to 373 K. R_b from MgTf₂ system are lower than LiTf in the room temperature. PMMA-EC-MgTf₂ sample conductivity is , PMMA-EC-LiTf₂ sample conductivity is
