Abstract


An attempt has been made on PVC/PEMA blend composite polymer electrolyte to find suitable wt% (X = 0, 5, 10, and 15) of inorganic filler Al2O3 by solution casting technique for the effective use in lithium battery application. The enhanced amorphous region of the polymer electrolyte has been identified from X-ray diffraction analysis. The addition of plasticizer (Diethylene Carbonate) significantly improves the flexibility of the medium, which helps for easy ionic motion. It has been found from the ac impedance analysis that the inorganic filler reduces the bulk resistance of the electrolytes and thus ionic is conductivity enhanced. The maximum ionic conductivity at room temperature, 0.11×10-4 S cm-1, was observed for the system PVC (5)/PEMA (20)/LiClO4 (8)/DEC (67) with 10 wt.% of Al2O3.

Keywords
