本工作提供了一种基于烷基和醚基的无环和环状的硫离子液体(ILS)的研究，该离子液体的阳离子与双{(三氟甲基)磺酰亚胺[TFSI]-或双(氟磺酰亚胺)[FSI]-配对作为反阴离子。本文报道了九种硫基离子液体的密度、粘度、电导率和热物性，包括相变行为和分解温度的热物理表征。用循环伏安法测定了离子液体在玻碳大圆盘电极上的电化学稳定性。所有离子液体都具有低熔点、低粘度和良好的导电性，可以作为潜在的储能装置的电解液。
This work provides a study based on acyclic and cyclic sulfonium ionic liquids (ILs) with alkyl and ether-functionality on the cation paired with the bis{(trifluoromethyl)sulfonyl}imide, [TFSI]- , or the bis(fluorosulfonyl)imide, [FSI]- , as the counter anion. Herein, thermophysical characterisation of nine sulfonium-based ILs concerning the density, viscosity and conductivity and thermal properties including phase transition behaviour and decomposition temperature is reported. The electrochemical stability of the ILs was also measured by cyclic voltammetry at a glassy carbon macro-disk electrode. All of the ILs showed low melting point, low viscosity and good conductivity and could serve as potential electrolytes for energy storage devices.
