A new route to the syntheses of N-(fluorosulfuryl)sulfonamide salts: Crystal structure of Ph4P+ [CF3SO2NSO2F]−

First-Principles Study of EMIM-FAFSA Molecule Adsorption on a Li(100) Surface as a Model for Li-Ion Battery Electrodes

“…Little experimental data is available for FTA salts. Of note, Beran et al 54 Figure 2g and cis in Figure 2h. The trans conformer is more stable, and the cis/trans energy difference is 2.66 kcal·mol −1 .…”

An improved high-power battery with increased thermal operating range: C–LiFePO4//C–Li4Ti5O12

“…LiFSI was first claimed as conducting salt with good anticorrosive properties for Li-ion batteries in 1995 [70], but this salt is difficult to prepare with the high purity that is mandatory for its use in Li-ion batteries [71]. Now that that this problem has been overcome [72,73], this salt has a considerable interest because of its thermal behavior, stability toward hydrolysis, and ionic transport behavior [74]: it is thermally stable up to 200 C, exhibits far superior stability toward hydrolysis than LiPF 6 , shows a conductivity that is larger than that of LiTFSI. Moreover, the corrosive effect of LiTFSI on the Al-collector at high voltage is not observed with LiFSI, provided that the salt is pure (i.e.…”

Installation of -SO2F groups onto primary amides

“…Therefore, the development of a new method for the assembly of N -fluorosulfonyl amides from cheap and abundant reagent is highly desirable. Herein, we report the first, to the best of our knowledge, SO 2 F 2 -mediated N -fluorosulfonylation [40–42] of amides by using DBU as base for the constructions of a series N -fluorosulfonyl amides (Scheme 1).…”
