離子液體是液體中的鹽。在某些情況下，該術(shù)語僅限于熔點(diǎn)低于某一任意溫度的鹽，如100°C(212°F)。普通液體如水和汽油主要由電中性分子組成，而離子液體主要由離子和短壽命的離子對(duì)組成。這些物質(zhì)被稱為液體電解質(zhì)、離子熔體、離子液體、熔鹽、液體鹽或離子玻璃。它們被稱為“未來的溶劑”和“設(shè)計(jì)溶劑”。離子液體被描述為具有許多潛在的應(yīng)用。它們是強(qiáng)大的溶劑和導(dǎo)電流體（電解質(zhì)）。在近環(huán)境溫度下為液體的鹽對(duì)電池應(yīng)用很重要，并且由于其極低的蒸汽壓力而被認(rèn)為是密封劑。
