We successfully prepared the nanocomposite solid polymer electrolytes based on poly(ethylene oxide) (PEO)/polyhedral oligomeric silsesquioxane-polyethylene glycol (POSS-PEG) complexed with LiN(SO<SUB>2</SUB>CF<SUB>3</SUB>)<SUB>2</SUB> (LiTFSI) salt and studied the effect of POSS-PEG (n=13.3) hybrid nanoparticles on structural, thermal, mechanical and ionic conductivity properties. The crystallinity of the nanocomposite solid polymer electrolytes has been characterized by X-ray diffraction (XRD). FTIR studies showed the evidence of the complexation between PEO, LiTFSI and POSS-PEG. Differential scanning calorimetry (DSC) was used to study their glass transition and melting behaviors and to measure their respective degrees of crystallinity. The degree of crystallinity reduced with POSS-PEG content, indicating restricted segmental motion of the polymer chains. The Young's modulus increased from 0.076 to 0.19MPa with the addition of POSS-PEG. Ionic conductivity studies reveal that solid polymer electrolyte with 30wt% of POSS-PEG has the highest ionic conductivity of 5.05x10<SUP>-5</SUP>S/cm at room temperature (23<SUP>o</SUP>C). The temperature dependence conductivity studies showed that the samples seemed to obey the Arrhenius behavior.
