The composite polymer electrolyte (CPE) membranes; comprising of poly(vinylidene fluoride-hexafluoropropylene) (PVdF-HFP); aluminum oxyhydroxide; (AlO[OH]n) of two different particle sizes 7 μm/14 nm and LiN(CF3SO2)2 as lithium salt were prepared using solution casting technique. The prepared membranes were subjected to XRD; impedance spectroscopy; compatibility and transport number studies. The incorporation of nanofiller greatly enhanced the ionic conductivity and the compatibility of the composite polymer electrolyte. Also LiCr0.01Mn1.99O4/CPE/Li cells were assembled and their charge-discharge profiles have been made at 70 °C. The film which possesses nanosized filler offered better electrochemical properties than those with micron sized filler. The results are discussed based on Lewis acid-base theory. © 2006 Elsevier Ltd. All rights reserved;
