Density The densities of the mixtures from MD simulations are provided in the SI (Table ) and are shown in Figure , alongside experimental data by Zhang et al. and this study (see Table in the SI). The simulated densities agree well with experimental values and exhibit strong temperature and composition dependence, increasing with lower temperatures and higher [Li][NTf 2 ] content. This trend is driven by the higher density of [Li][NTf 2 ] (2.15 g cm -3 at 20 • C) compared to G3 (0.986 g cm -3 at 25 Figure : Densities of the investigated mixtures as a function of the mixing ratio and the temperature. Experimental data are given for several mixing ratios at 303 K by Zhang et al. and for the equimolar mixture at 303 K and 283 K this study (see Table of the SI).
