Figure 2. The ion solvation structures in the bulk phase and under nanoconfinement. (A-C) Radial distribution functions (RDF) and coordination numbers of relative water molecules surrounding Li⁺ in electrolyte systems at concentrations of 1 m, 10 m, and 21 m, with spatial distribution function (SDF) as insets; (D-F) The RDF, coordination numbers, and SDF of relative water molecules surrounding TFSI^- at the same concentration.
