        abstract = {Sodium-ion based PEO-80:NaPF6-10:Al2O3-10 dispersed solid electrolyte system was synthesized through solution casting method is presented in this paper. Structural, morphological and thermal properties have been carried out by using techniques like XRD, SEM, FTIR, DSC and Impedance Spectroscopy is employed to study the electrical and dielectrical behavior of the system.  FTIR studies have confirmed the presence of various vibrational modes and the interactions among molecules of  polymer, salt, and nano-dispersoid. The DSC investigations indicate the melting points of pure and dispersed systems and revealed the absence of any phase transition in all the three systems. X- Ray diffactograms provide the crystalline nature of  pure PEO, NaPF6, Al2O3, and PEO-NaPF6-Al2O3 system. SEM  micrographs visualize the surface morphology of the mixed system and the distribution of  Al2O3 within the polymer matrix. Impedance analyses is carried out to evaluate the dc ionic conductivity and activation energy. The variation of  real and imaginary components of ac conductivity, dielectric constant, dielectric loss and electric modulus with temperature  and  frequency show the existence of various types of polarizations at low frequencies disappear at high frequency region and enhanced dc conductivity is attributed to the increased concentration of charge carriers in the dispersed system  and increased hopping frequency of mobile charge carriers  could be responsible for higher ac conductivity at higher frequencies.},
