The activity coefficients at infinite dilution (γi∞) of 30 organic solutes (including alkanes, aromatics, acetonitrile, acetone, tetrahydrofuran, ethyl acetate, and chloromethanes) in the ionic liquid (IL) 1-butyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide ([BMMIM][NTf2]) were measured over the tempera...
The thermophysical behavior and molecular origins of dynamic viscosity (η) non-ideality in binary mixtures of acetonitrile (ACN) with six tertiary alkanolamines, namely dimethylethanolamine (DMEA), dimethylpropan-1-olamine (DMPA-1), dimethylpropan-2-olamine (DMPA-2), methyldiethanolamine (MDEA), ethyldiethanolamine (ED...
Ionic liquids have attracted considerable attention as safe electrolytes for next-generation lithium batteries because of their nonflammability and high thermal stability. In this study, an ether-functionalized tetrahydrothiophenium ionic liquid, 1-(2-methoxyethyl)tetrahydrothiophenium bis(trifluoromethanesulfonyl)am...
The present work reports a comparative investigation of 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (EMITf) an ionic liquid and tetraethylene glycol dimethyl ether (TEGDME) a glyme-based solvent, highlighting their roles in modulating physical and electrochemical properties of Na-ion-conducting gel polymer...
Experimental measurements and molecular dynamics (MD) simulations study the structural and rheological properties of a model fluorinated ester electrolyte, methyl 3,3,3-trifluoropropionate (MTFP) with LiFSI, over a wide concentration range (0.1–2.3 mol/kg). MD simulations using a calibrated Generalized AMBER Force Fi...
Poly(ionic liquid)/ionic liquid mixtures are promising polymer electrolyte materials, yet their ion transport mechanisms remain unclear. Here, we investigate the thermal, viscoelastic, and dielectric properties of mixtures of poly(1-butyl-3-vinylimidazolium bis(trifluoromethanesulfonyl)imide) (PC4-TFSI) and 1-butyl-3...
