In the present paper new generation of imidazole-derived lithium salts (LiTDI—lithium 4,5-dicyano-2-(trifluoromethyl)imidazolide, LiPDI—lithium 4,5-dicyano-2-(pentafluoroethyl)imidazolide and LiHDI—lithium 4,5-dicyano-2-(n-heptafluoropropyl)imidazolide) applied in a model liquid electrolyte, with propylene carbonate used as a solvent, is described. Room temperature ionic conductivities measured by Impedance Spectroscopy are as high as 10⁻² to 10⁻³ S cm⁻¹ for the 0.1–1 mol dm⁻³ salt concentration range. Lithium cation transference numbers calculated using the Bruce–Vincent method exceed 0.4 at salt concentration equal to 1 mol dm⁻³. Interface resistance measurements showed good stability at high—0.5 mol dm⁻³ or low—0.01 mol dm⁻³ salt concentrations. Ionic associations were estimated using Fuoss–Kraus semiempirical method revealing relatively low association rates. The effect of anion structure on ionic interactions and electrochemical characteristics of the studied electrolytes is discussed.

在本文中，新一代咪唑衍生的锂盐（LiTDI-4,5-二氰基-2-（三氟甲基）咪唑啉锂，LiPDI-4,5-二氰基-2-（五氟乙基）咪唑啉锂和LiHDI-锂4，描述了在模型液体电解质中使用碳酸亚丙酯作为溶剂施加的5-二氰基-2-（正七氟丙基）咪唑啉。在0.1–1 mol dm ^-3盐浓度范围内，通过阻抗谱测量的室温离子电导率高达10 ^-2至10 ^-3  S cm ^-1。在盐浓度等于1 mol dm ^{-3的情况下，}使用Bruce-Vincent方法计算的锂阳离子转移数超过0.4 。界面电阻测量显示出在高-0.5 mol dm时的良好稳定性^-3或低至0.01 mol dm ^-3盐浓度。使用Fuoss-Kraus半经验方法估计离子缔合，揭示了相对较低的缔合率。讨论了阴离子结构对所研究电解质的离子相互作用和电化学特性的影响。
