“…This mole fraction of binary {PYR 14 TFSI + GBL} mixture was selected since our previous studies indicated that this composition has the highest specific conductivity which is one of the parameters that governs performance of the lithium-ion batteries. 26 For convenience, in this work the electrolyte 1 mol · dm −3 LiTFSI in {PYR 14 TFSI + GBL} (at 0.2 IL mole fraction) will be indicated as PYR 14 TFSI/GBL/LiTFSI.

Ternary electrolyte composed of 1-butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide ionic liquid (PYR 14 TFSI), γ-butyrolactone (GBL) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) and anatase TiO 2 nanotube arrays (NTAs) electrode are investigated for the application in new generation of lithium-ion batteries (LIBs). The electrical conductivity and viscosity are measured in the whole composition range at several temperatures. Also, cyclic voltammetry experiments are performed at different temperatures and scan rates. At all scan rates, up to 100 mV · s −1 Ti 4+ /Ti 3+ redox peaks appear designating exceptionally fast intercalation/deintercalation reaction. At the end of cycling the intercalation/deintercalation capacity was 144.8/140.7 mAh · g −1 at current rate 3 C. The diffusion coefficient for Li + extraction from TiO 2 nanotubes (NTs) have been calculated for temperatures from (25 to 55) • C. Activation energy for diffusion was found to be 54.7 kJ/mol (0.57 eV The rapid development of portable electronic devices and technologies significantly increased demand for the next generation of energy storage systems.1 Because of enhanced energy and power density, efficiency and long life, LIBs are currently one of the most promising energy storage devices.2,3 Improvement of safety standards and low impact on human health and environment is essential for large-scale application of LIBs. 4 Safety concerns related to utilization of highly volatile and flammable organic solvents in commercial cells can be addressed by introducing ionic liquids (ILs) as emerging class of fluids.5 Numerous advantages of ILs such as negligible vapor pressure and high chemical and thermal stability make them ideal candidates for their application in LIBs. Potential application of ILs based on a combination of the pyrrolidinium (PYR + ) cation and bis(trifluoromethanesulfonyl)imide (TFSI -) anion as electrolytes in LIBs with long term cycling stability and very good capacity utilization, has been confirmed by several research groups. [6][7][8][9][10][11][12] Nevertheless, the utilization of IL-based electrolytes is usually limited by their high viscosity, which reduces transport capabilities and slows down the chemical processes that occur in these solvents. Mixing of ionic liquids with molecular solvents such as organic carbonates or lactones can reduce viscosity of applied electrolyte. 12-15Among other aprotic solvents, γ-butyrolactone (GBL) is usually applied in new generation of LIBs and other electrochemical devices. Besides its low cost, GBL has wide liquidus range and better thermal stability comparing to alkyl carbonate solvents. 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 DC...

“…The magnitude and sign of V E data is a cumulative effect of contributions due to From Figure 3, we can see that the lowest V E value is very close to the ideality in the system {[bmpyrr][NTf 2 ] + GBL}, 15 indicating that there is no significant change in the volume of the systems after mixing equimolar amounts of the components. The higher negative deviations from the ideality, observed for the {[bmpyrr][NTf 2 ] + DEC} system, are the result of stronger intermolecular interactions of the IL with DEC or their favorable packing effect.…”

“…During our systematic research on the thermodynamic properties of ILs binary mixtures with a molecular solvent, 1butyl-1-methylpyrrolidinium-based ionic liquid, [bmpyrr]-[NTf 2 ], was studied in the mixtures with GBL. 15 By reducing viscosity and altering other physicochemical properties, it was shown that this mixture could be applied as an electrolyte for Li-ion batteries. 21 Therefore, as a continuation of our previous studies toward the understanding and comprehension of the basic properties of (IL + molecular solvent) binary mixtures, the volumetric and transport properties of 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ionic liquid, [bmpyrr][NTf 2 ], with DEC were for the first time investigated in this work.…”

Densities, viscosities, and electrical conductivities were determined and discussed for a binary mixture containing 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ionic liquid, [bmpyrr][NTf2], and diethyl carbonate (DEC) as a function of temperature (T = 293.15–323.15 K) at atmospheric pressure (p = 0.1 MPa) over the entire range composition. Based on experimental density data, the related excess molar volumes were calculated and fitted using Redlich–Kister’s polynomial equation. The Casteel–Amis equation was used to correlate data obtained from electrical conductivity measurements. The effect of viscosity on electrical conductivity was discussed by the Walden rule. The Bahe–Varela theory, derived from the the pseudo-lattice model, has been successfully applied to explain the influence of the mixture composition on electrical conductivity. Based on physicochemical characterization supported with computational simulations for binary mixtures ([bmpyrr][NTf2] + DEC), the interactions between these components were discussed.
