ABSTRACT

This paper is the second in a series in which thermodynamic properties of solutions of lithium bis(fluorosulfonylimide (LiFSI) are investigated. The solvents that are considered here are: methyl tert-butyl ether (MTBE) and water (H2 O), which are good solvents for LiFSI, and anisole, which is an anti-solvent for LiFSI. The solubility of LiFSI in MTBE, as well as in the binary solvent mixture MTBE-anisole was measured at temperatures between 283 and 303 K and concentrations of LiFSI up to 0.47 mol mol-1 . Furthermore, the liquid-liquid equilibrium of the system LiFSIMTBE-H2 O was studied at 293 K and ambient pressure. Moreover, the density and shear viscosity of solutions of LiFSI in MTBE were studied at temperatures between 273 and 308 K and concentrations of LiFSI up to 0.4 mol mol-1 .
