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
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.
