Liquid structures of Li/Mg/Cs-TFSA (TFSA: bis(trifluoromethylsulfonyl) amide, N(SO2CF3)(2)(-)) molten-salt systems have been investigated by Raman spectroscopy and high-energy X-ray diffraction. The Raman spectroscopic measurements indicate that the cis-conformer of the TFSA anion is more favorable than the trans-conformer in the molten salts containing Li+ and/or Mg2+, whereas the latter is dominant for a pure Cs[TFSA] molten salt. The present reverse Monte Carlo (RMC) structural modelling suggests that the coordination number of the anion around Mg, NMg-anion, decreased in Li0.1Mg0.1Cs0.8[TFSA](1.1) molten salt compared to that in Mg0.1Cs0.9[TFSA](1.1). The Mg-anion distance under the coexistence of Li+ is found to be about 10-15% longer than that without Li+ at around NMg-anion similar to 1.5, which means the increase of free volume around Mg cations in the Li-contained molten salt. Thus, the electrodeposition of Mg in alkali-TFSA molten salts would be facilitated under the coexistence of Li cations.
