Abstract

The polyvinylidenefluoride (PVdF) based novel polymer electrolytes have been prepared by solution casting technique for solid state rechargeable magnesium batteries. Tetraglyme and tetrabutyl ammoniumchloride were used respectively as plasticizer and filler. The Mg(ClO $_{4})_{4}$ was used as conducting source. A.c. impedance spectroscopy results reveal that 5 wt% TBACl containing electrolyte show the maximum conductivity of 4.32 × 10-4 S/cm at ambient temperature. This electrolyte was electrochemically stable upto 1.5 V which was observed through linear sweep voltammetry. X-ray diffractograms studies suggest that the electrolytes are completely in amorphous phase. The improved entanglement like surface morphology was well observed for 5 wt% TBACl containing electrolyte by scanning electron microscope. The activation energy and coherence length were calculated.
