Abstract: 

Composite polymer electrolyte films consisting of polyethylene glycol (PEG), Mg(CH3COO)2 and Al2O3 particles have been prepared by solution casting technique. The X-ray diffraction patterns of PEG-Mg(CH3COO)2 with Al2O3 ceramic filler, indicates the decrease in the degree of crystallinity with increasing concentration of the filler. The role of ceramic phase is to reduce the melting temperature which is ascertained from the DSC. The effect of ceramic filler on the conductivity of the polymer electrolyte was studied. The maximum ionic conductivity has been observed for 10 wt% of Al2O3 at room temperature (303 K). The transference number data indicated the dominance of ion-type charge transport in these composite polymer electrolytes. Using this (PEG-Mg(CH3COO)2-Al2O3) (85–15–10) electrolyte, solid-state electrochemical cell was fabricated and their discharge profiles were studied under a constant load of 100 kΩ. Several cell profiles associated with this cell were evaluated and are reported. Copyright © 2013 VBRI press.
