Fig. 3: Solvation state of Li⁺ in the DMA-DEE biphasic system.

a, c Snapshots of the MD simulation of the top phase (a) and bottom phase (c). b, d Representative Li⁺ solvation structure in the top phase (b) and bottom phase (d) extracted from the cMD simulations. e Li⁺ intermolecular RDFs in the top phase, including Li⁺/O (TFSI⁻), Li⁺/N (TFSI⁻), Li⁺/O (DMA), Li⁺/N (DMA), and Li⁺/O (DEE). f Li⁺ intermolecular RDFs in the bottom phase, including Li⁺/O (TFSI⁻), Li⁺/N (TFSI⁻), Li⁺/O (NO3⁻), Li⁺/O (DMA), Li⁺/N (DMA), and Li⁺/O (DEE).
