摘要

Abstract

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.
