Density, excess properties, electrical conductivity and viscosity of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide + γ-butyrolactone binary mixtures

Ideal and non-ideal behaviour of {1-butyl-1-methylpyrrolydinium bis(trifluoromethylsulfonyl)imide + γ-butyrolactone} binary mixtures

“…Positive values of these properties for both components also indicate weaker interactions between GBL and IL compared to the pure components. This is the opposite trend to the one obtained in {[bmim][NTf 2 ] + GBL} binary mixtures [52].…”

“…The change of [bmpyrr][NTf 2 ] partial molar volume is negligible, while the values V 2 are increasing with the increase of the ionic liquid mole ratio in the mixture. In figure S3 values of partial molar volumes are graphically compared with the values calculated for the system containing [bmim][NTf 2 ] [52].…”

“…These plots are placed below the ''ideal'' KCl line. The value of the slope a of each Walden plot, log(K m ) vs log(g À1 ), is 0.956 for the mixtures with {[bmim][NTf 2 ] + GBL} [52] and 0.941 for those with [bmpyrr][NTf 2 ]. This indicates the existence of tight ion pairs in the solution, which do not undergo significant separation under the influence of an electric field and, therefore, do not contribute to ion current.…”

Electrochemical Performance of Anatase TiO2Nanotube Arrays Electrode in Ionic Liquid Based Electrolyte for Lithium Ion Batteries

“…16 In our previous papers we demonstrated that binary mixture of 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide, (IM 14 TFSI), and GBL has around 20% higher specific conductivity at low IL mole fractions compared to IM 14 TFSI + propylene carbonate (PC) binary mixture. 15,17 Xu et al observed similar trend in the case of 1-ethyl-3-methylimidazolium dicyanamide (IM 12 DCA) binary mixtures with GBL and PC. 18 Because of high stability against oxidative decomposition, GBL was investigated as co-solvent added to improve solubility and conductivity of lithium bis(oxalate)borate-based electrolyte.…”

“…Furthermore, the study of physicochemical properties of binary mixtures of ILs + MOS furnishes extensive information about molecular interaction (ion dipole, dipole-dipole, hydrogen bonding) exist in their mixtures [8][9][10][11][12].
