We report here the preparation and characterization of an all-solid state polyethylene oxide (PEO) composite electrolyte from PEO(375)–SiO2, high molecular weight PEO (MW = 600 K) and LiClO4 (O/Li = 16/1). Oligomeric PEOs, with ethylene oxide (EO) repeat units 6–9 (<MW> = 375 g/mol), were chemically grafted (~ 30 wt.%) to fumed silica (A380) using a trimethoxy PEO(375)-silane. The surface grafted PEO chains were disordered (no crystallization) and less mobile than the free chains, with the glass transition temperature (Tg) increasing from − 90 °C [PEO(375)-silane] to − 54 °C [PEO(375)–SiO2]; addition of LiClO4 (O/Li = 8/1) further raised Tg to − 34 °C. Nanocomposite electrolytes with good dimensional stability were obtained by blending 14-wt.% PEO(375)–SiO2 with semicrystalline PEO(600 K)/LiClO4 (O/Li = 16/1). Conductivities (σ) were 10 to 4 times greater [between 10 °C (σ = 2.1 × 10− 8 S/cm) and 40 °C (σ = 1.1 × 10− 5 S/cm), respectively] than for neat PEO(600 K) or for composite electrolytes having the same amount of native fumed silica, SiO2. No conductivity improvements were observed above Tm or for amorphous PEO(600 K)/LiClO4 (O/Li = 8/1) with addition of SiO2 or PEO(375)–SiO2.}, number={39-40}, journal={SOLID STATE IONICS}, author={Zhang, Hanjun and Maitra, Prithwiraj and Wunder, Stephanie L.}, year={2008}, month={Mar}, pages={1975–1983} }

It was found that steric effects limited polyelectrolyte surface loading even when large amount of silane molecules were grafted by forming a cross-linked structure. The results indicate that large surface area is an important factor to achieve high-surface loading of ionic moieties. Composite electrolytes were prepared by dispersing these SICs in aprotic solvents. The effects of filler content and solvent on ionic conductivity were investigated.}, number={2}, journal={JOURNAL OF POWER SOURCES}, author={Zhang, Hanjun and Zhang, Xiangwu and Shiue, Eric and Fedkiw, Peter S.}, year={2008}, month={Mar}, pages={561–565} }
