Polymer electrolytes, which hold the key of successful operation of all solid state ionic devices, have been investigated. An amorphous polymer was used to facsimile fast ion transport in the gel polymer electrolytes (GPE) and room temperature conductivity >10(-3) S/cm can be attained. Further, these electrolytes were transformed into composites by dispersing inorganic particles of gamma-Al2O3 (11 nm in size) in varying wt.%. An enhancement in the conductivity for an optimum concentration using LiClO4 LIS a salt can described in terms of free charge carrier concentration, while the other family of Lithium salts viz. LITE Lilm, LIBETI decreases the conductivity marginally. FTIR spectroscopy Supports the observed decrease in terms of more association between fillers and salts. It has been realized that the mechanical integrity of these composites increases manifold, without affecting the conductivity, significantly. (C) 2007 Elsevier B.V. All rights reserved.
