Electric conductivity and rheological responses of colloidal electrolytes consisting of lithium bis(trifluoromethanesulfon) imide, polyethylene glycol (PEG) oligomer, and fumed silica have been investigated. Incorporating silica could improve ionic conductivity of the electrolytes at the same lithium/oxygen ratios. The colloidal electrolytes demonstrate a sol to gel transition with increasing silica content while they exhibit shear thickening behaviors during steady flow at intermediate range of strain rate. The presence of lithium salt, on the one hand, could lower the crystallinity of PEG or forbid the crystallization and on the other hand, interferes the chain adsorption on the surface of silica. Furthermore, lithium salt strongly retards the segmental relaxation of PEG in the colloidal electrolytes.

已经研究了由双（三氟甲磺酸锂）酰亚胺，聚乙二醇（PEG）低聚物和气相二氧化硅组成的胶体电解质的电导率和流变响应。在相同的锂/氧比下，掺入二氧化硅可以改善电解质的离子电导率。胶态电解质显示出随着二氧化硅含量的增加，溶胶到凝胶的转变，而它们在应变速率的中间范围内稳定流动期间表现出剪切增稠行为。锂盐的存在，一方面会降低PEG的结晶度或阻止结晶，另一方面会干扰硅石表面的链吸附。此外，锂盐强烈阻碍了胶体电解质中PEG的节段松弛。
