在提高电化学双电层电容器（EDLC）的能量和功率密度的范围内，具有增强的操作电压的高性能电解质的开发是势在必行的。配制含有离子液体与有机分子溶剂的混合物是追求开发高度电化学稳定和安全的材料同时保持高功率应用的快速传输性能的重要策略。在这项工作中，我们报告的物理化学调查到二元混合物含有离子液体1-丁基-1-甲基吡咯烷双{（三氟甲基）磺酰基}酰亚胺与一个单腈溶剂，丁腈，和两个二腈溶剂，戊二腈和己二腈，作为潜在的电解质EDLC。的热，体积和运输性能的二元混合物的电解质组合物和温度的函数进行了研究。此外，电解质组合物，表现出最高的电导率为每个二元混合物进行了测定，并报告其电化学稳定性使用玻璃碳macrodisk电极。
In the scope of improving the energy and power densities of electrochemical double layer capacitors (EDLCs), the development of high performance electrolytes with enhanced operative voltages is imperative. The formulation of mixtures containing ionic liquids with organic molecular solvents is an important strategy in the pursuit of developing highly electrochemically stable and safe materials while retaining fast transport properties for high power applications. In this work, we report on the physical chemical investigations into binary mixtures containing the ionic liquid 1-butyl-1-methylpyrrolidinium bis{(trifluoromethyl)sulfonyl}imide with one mononitrile solvent, butyronitrile, and two dinitrile solvents, glutaronitrile and adiponitrile, as potential electrolytes for EDLCs. The thermal, volumetric, and transport properties of the binary mixtures are investigated as functions of the electrolyte composition and temperature. Furthermore, the electrolyte composition which exhibits the highest conductivity for each of the binary mixtures was determined, and its electrochemical stability is reported using a glassy carbon macrodisk electrode.
