WebJul 1, 2024 · Specifically, some solvent molecules will combine with cations and/or anions to form a solvation sheath, forming solvent-separated ion pairs (SSIPs), solvent-shared ion pairs, contact ion pairs (CIPs) or aggregates based on the salt-solvent interaction [16]. The solvation structures could be affected by the solvent type and the salt concentration. WebAt the same time, a peak emerges at a higher wavelength (930–935 cm −1) in both LiTFSI- and LiFSI-based electrolytes, which is attributed to the DMC molecules bonded in the Li + solvation sheath. 50 Due to the large size and low charge density, FSI − and TFSI − are poor in the anion solvation. 29,33 Therefore, solvation in this paper ...
