Experimental densities, electrical conductivities and viscosities for ionic liquids 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [bmim][NTf2] and 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide [bmpyrr][NTf2] binary mixtures with selected organic acyclic carbonates were measured at atmospheric pressure (p = 0.1 MPa) in the temperature range from T = (293.15 to 323.15) K over the whole composition range. From the experimental density data, the related excess molar volumes were calculated and fitted using Redlich-Kister’s polynomial equation. The thermal expansion coefficients were also calculated from the acquired experimental density values. The influence of molecular solvent structure and effects of the lactones bulky on the nature of interactions and hydrogen bonding in the studied binary mixtures with [bmim][NTf2] and [bmpyrr][NTf2] were discussed. Based on calculated values for ionicity, potential applications of these mixtures as electrolytes for lithium-ion batteries were examined.
