An attempt has been focused to develop a new aluminum ion conducting non aqueous polymer electrolyte for high power rechargeable batteries having applications in rapidly growing markets, such as laptops, handy tele communication equipments, electric vehicles, camcorders, etc. These features have given a thrust to develop a suitable Nano composite GPE based on  PAN as polymer host and Sodium fluoride (NaF) as dopant salt and Al۲O۳ as nano filler in the form of thin films through solution casting technique consuming N,N-dimethyl formamide (DMF) as a common solvent. NCGPE films have been prepared by solution casting technique. The XRD pattern of ۷۰PAN-۳۰NaF with addition of wt% Al۲O۳ ceramic filler indicates reducing degree of crystallinity. Using IR studies revealed that the complexation of the polymer poly (acrylonitrle) with NaF. The conductivity of the GPEs was studied with enhancement of nano fillers. The sample containing ۳% of Al۲O۳ exhibits the highest conductivity of ۴.۸۲x۱۰-۳S cm-۱ at room temperature (۳۰۳K) and ۵.۹۶x۱۰-۳S cm-۱ at ۳۷۸K. With the help of Wagner’s polarization technique electronic (te) and ionic (ti) values can be determined.To determine profiles of discharge characteristics (۷۰PAN-۳۰NaF-۳wt% Al۲O۳) NCGPE solid-state electrochemical cell was fabricated and various cell profiles were evaluated
