Abstract

Ionogel electrolytes at medium temperatures were prepared by composite of ionic liquid [1-butyl-3-methylimidazole][bis-(fluoromethanesulfonyl) amide] ([BMIM][TFSI]) with the proton-conducting inorganic solid acid CsHSO4. The incorporation of only 10 wt.% of the ionic liquid into the solid acids drastically increased the conductivity of solid acids over a wide temperature range. The ionogel electrolytes contained up to 40 wt.% of the ionic liquid within their inorganic CsHSO4 networks and had an ion conductivity of 2 × 10- 2 S/cm.
