Figure 8. (A) Schematic of three general categories of solvent-salt interactions. (B) Distribution of the Li⁺ solvates for the LiPF₆-THF (2.0 M) from MD simulations. This figure is quoted with permission from Chen et al.^[76]. (C) Reduction potentials of key electrolyte components with the first Li⁺ solvation shell, which shows that fluorinated salts will decompose preferentially. This figure is quoted with permission from Chen et al.^[76]. (D and E) Calculated electronic structures (projected density of states, pDOS) of dilute D and concentrated E LiTFSA/AN electrolytes, which suggests a gradual transfer of LUMO to anion with increasing concentration. This figure is quoted with permission from Yamada et al.^[94]. (F) Charge/discharge profiles of Na||HC(hard carbon) cells using the concentrated NaFSA/TMP electrolyte. This figure is quoted with permission from Wang et al.^[95]. (G) Cycling performance with different electrolytes at 2 C and 25 °C. This figure is quoted with permission from Piao et al.^[96].
