Poly(ethylene oxide)-lithium bis(oxalato)borate based nanocomposite polymer electrolytes

This work focuses on the characterization of series of solid nanocomposite polymer electrolytes consisting of poly(ethylene oxide) (PEO), aminopropyl hepta isobutil polyhedral oligomeric silsesquioxane (APHIB POSS) and lithium bis(oxalato)borate (LiBOB). Nanocomposite were prepared by melt intercalation method with different EO:Li molar ratios and at different APHIB POSS loadings. Differential scanning calorimetry (DSC) shows that an addition of LiBOB and APHIB POSS causes an important decreases of the crystallinity and melting temperatures of PEO, while glass transition temperatures show higher values. The influence of LiBOB and APHIB on the PEO crystallinity was also confirmed by Fourier transform infrared spectroscopy (FTIR). Thermal stability as one of the key issues of the polymer electrolytes was investigated by non-isothermal thermogravimetry. Thermogravimetric analysis (TGA) shows a more complex non-isothermal degradation of prepared samples compared to pure PEO. However, polymer electrolytes remaind thermal stable enough for their suitable applications in electrochemical devices. Electrochemical impedance spectroscopy reveals that LiBOB and APHIB POSS incorporation have positive influence on the ionic conductivity of PEO at room temperature. Considering the ionic conductivity of nanocomposites the optimized system was determinated.
