In the present work, polymer electrolyte (PE) film consisting of poly(vinyl alcohol) (PVA) with magnesium bromide (MgBr2) as electrolytic salt, tetraethylene glycol dimethyl ether (TEGDME) as plasticizer and Li2O at different concentration (0.02, 0.04, 0.06 wt.%) as the filler has been prepared by solution casting technique. The polymeric film was flexible and self-standing with proper mechanical strength and studied for application in a solid-state rechargeable magnesium battery. The interactions between the filler and PVA chains are studied by X-ray and thermogravometric analyses. The conductivity increased with addition of filler reached to ∼10–5 S·cm–1 at 0.04 wt.% Li2O. The frequency dependence of ac conductivity obeys Jonscher power law. The estimated value of Mg+2 ion transference number is found to be 0.7 for high conducting film. A solid state battery based on the optimum polymer electrolyte with a configuration Mg|PE V2O5 has exhibited an open circuit voltage of 1.5 V. Also this battery has exhibited a discharge capacity ≈6.11 mA h. The discharge characteristics are found to be satisfactory as a laboratory cell.
