Lithium bis(trifluoromethane)sulfonimide (LiTFSI) is a hydrophilic organic salt that has many uses in electric and electronic systems. Its bis(trifluoromethane)sulfonimide anion, often referred to as bistriflimide, has the useful property of coordinating weakly with cations.
LiTFSI是一种亲水性有机盐,在电气和电子系统中有许多用途。其双(三氟甲烷)磺酰亚胺阴离子,通常称为双氟利酰亚胺,具有与阳离子弱配位的有用特性。
LiTFSI ‘s other important property is its extremely high solubility in water: 21 molal or ≈6 kg/L of solution. Because of its solubility, it has been explored as an electrolyte for lithium-ion batteries, solar cells, and similar applications since at least the late 1980s. LiTFSI is a safer material than the formerly used salt, lithium hexafluorophosphate (LiPF6).
LiTFSI的另一个重要特性是其在水中的溶解度极高:21摩尔或≈6 kg/L溶液。由于其溶解性,至少自 1980 年代后期以来,它就已被探索为锂离子电池、太阳能电池和类似应用的电解质。LiTFSI是一种比以前使用的盐六氟磷酸锂(LiPF6)更安全的材料。
