Density measurements with temperature for the eight shortlisted ILs. (A) [FSI] anion-based. (B) [TFSI] anion-based. Markers represent experimental data. Lines represent the correlation fits of density as a function of temperature (T) using: $\rho =A+BT+C{T}^2$ , where correlation coefficients are A (g cm^-3), B (g cm^-3 K⁻¹), and C (g cm^-3 K⁻²). See Supplementary Material for details and reference of curve fits.
