(PEO+KNO3+Nano Al2O3) based Composite Polymer Electrolytes (CPE) has been prepared by using solution casting technique. In this technique, Poly (ethylene oxide) (PEO) and KNO3salt were dissolved separately in methanol and they were mixed together. Nano alumina (Al2O3) (particle size ~10nm) was doped to mixed solution and stirred for 24hrs. X-ray diffraction (XRD) technique has been obtained to determine complexation of salt and polymer in composite polymer electrolytes. Ionic and electronic transference numbers of these composite polymer electrolytes has been calculated by using Wagner’s polarization technique. The DC Conductivity of these composite polymer electrolytes has been evaluated in the temperature range of 303-373 K.
