dc.description.abstractEnThe Raman spectra of (1 - x)(BMITFSI), xLiTFSI ionic liquids, where 1-butyl-3-methylimidazolium cation (BMI+) and bis(trifluoromethane-sulfonyl)imide anion (TFSI-) are analyzed for LiTFSI mole fractions x < 0.4. As expected from previous studies on similar TFSI-based systems, most lithium ions are shown to be coordinated within [Li(TFSI)2]- anionic clusters. The variation of the self-diffusion coefficients of the 1H, 19F, and 7Li nuclei, measured by pulsed-gradient spin-echo NMR (PGSE-NMR) as a function of x, can be rationalized in terms of the weighted contribution of BMI+ cations, TFSI- free anions, and [Li(TFSI)2]- anionic clusters. This implies a negative transference number for lithium.
