An imidazolium-based zwitterion containing two oxyethylene units was obtained as a colorless liquid at room temperature. The equimolar mixture of the liquid zwitterion and lithium bis(trifluoromethylsulfonyl)amide showed an ionic conductivity of over 10−4 S cm−1 at 80 °C, which was higher than those of mixtures composed of analogous solid zwitterions.
