Fig. 3: Property calculations.

The radial distribution functions (RDF, g(r)) of (a) Li⁺ − O_DMC, (b) \({{{{\rm{Li}}}}}^{+}-{{{{\rm{O}}}}}_{FS{I}^{-}}\), and c. Li⁺ − O_BTFE, along with (d) the corresponding coordination numbers (CN) in diluted, concentrated LiFSI/DMC electrolytes and localized highly concentrated electrolytes. e The vibrational density of states (vDOS) of aqueous electrolytes with varying concentrations of LiTFSI, showing the blue shift of the O-H stretching mode from ^∼3400cm⁻¹ to ^∼3600cm⁻¹ with increasing concentration, indicating the isolation of water molecules by the ionic network formed by Li⁺ and TFSI⁻. f The vDOS of DME-based electrolytes with varying concentrations of LiFSI, showing a mode at ^∼750cm⁻¹ shifting to higher wavenumbers as the LiFSI concentration increases. The C, H, O, N, S, F and Li atoms are in gray, white, red, blue, yellow, green and pink, respectively.
