A comparative study on the effects of salt and filler on transport and structural properties of organic–inorganic hybrid electrolytes

摘要: Organic–inorganic hybrid electrolytes based on the reaction of tri-block copolymer poly(propylene glycol)-block-poly(ethylene glycol)-block-poly(propylene glycol) bis(2-aminopropyl ether), poly(ethylene glycol diglycidyl ether, and (3-glycidyloxypropyl)trimethoxysilane doped with LiClO4 SiO2 nanoparticles were synthesized by a sol–gel process. The structural dynamic properties materials thus obtained systematically investigated Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, alternate current impedance, 13C solid-state NMR measurements. A maximum ionic conductivity 3.2 × 10−5 S cm−1 was at 30 °C for solid electrolyte [O]/[Li] ratio 16 7 wt% nanoparticles. Vogel–Tamman–Fulcher-like temperature dependence observed electrolytes, implying that diffusion charge carriers assisted segmental motions polymer chains.
