“…Secondly, in order to lower melting temperatures, we aimed at alkali bis(fluorosulfonyl)amides, MFSAs. For some MFSAs, the route of synthesis and the crystal structures have been studied [5][6][7][8]. Especially, LiFSA is expected to be used as electrolyte salts for lithium batteries and has been useful as an electrolyte salt for lithium batteries with PEO-based gel [9,10], EC/DMC [11] and ionic liquid [12] electrolytes for lithium ion batteries with LiFePO 4 cathodes.…”

Four kinds of ternary phase diagrams of alkali bis(fluorosulfonyl)amides, LiFSA-NaFSA-KFSA, LiFSA-NaFSA-CsFSA, LiFSA-KFSA-CsFSA and NaFSA-KFSA-CsFSA, have been constructed. All the ternary systems possess the only one eutectic point around equimolar composition with the temperature of 309-318 K. The electrochemical window of the eutectic LiFSA-KFSA-CsFSA ((x Li ,x K ,x Cs)=(0.30,0.35,0.35)) is as wide as 5.4 V at 323 K with the cathode limit being lithium metal deposition. The electrochemical window of the eutectic NaFSA-KFSA-CsFSA ((x Na ,x K ,x Cs)=(0.40,0.25,0.35)) is 4.9 V at 323 K with sodium metal 2 deposition as the cathode limit reaction.

“…These ionic liquids are unique in the point that they are inorganic compounds. So far, the melting points and the crystal structures of LiFSI, KFSI, CsFSI, and the melting points of NaFSI and RbFSI have been reported [8][9][10].…”

Thermal properties of alkali bis(fluorosulfonyl)amides, MFSI (M = Li, Na, K, Rb, Cs), have been investigated. Binary phase diagrams of LiFSI-KFSI and NaFSI-KFSI systems have been constructed. Eutectic point for LiFSI-KFSI is 338 K at (xLi, xK) = (0.45, 0.55) and, that for NaFSI-KFSI is 330 K at (xNa, xK) = (0.45, 0.55). The electrochemical window of the eutectic LiFSI-KFSI is as wide as 6.0 V at 348 K with the cathode limit being lithium metal deposition. The electrochemical window of the eutectic NaFSI-KFSI is 5.0 V at 340 K with sodium metal deposition at the cathode limit. These new inorganic ionic liquids are highly promising for various electrochemical applications.

Single crystals of potassium hydrogentartrate, (2R,2R)‐KO2C(CHOH)2CO2H, were taken from a three‐year‐old wine bottle. The structure was determined by low‐temperature single‐crystal X‐ray diffraction analysis using a Siemens SMART diffractometer. (2R,2R)‐KO2C(CHOH)2CO2H crystallizes in the orthorhombic space group P212121 with Z = 4 and unit cell dimensions a = 7.6065(5), b = 7.7599(5), and c = 10.6054(7) Å. The structure of an isolatedhydrogentartrate anion, (2R,2R)‐[O2C(CHOH)2‐CO2H]−, was calculated at the semiempirical AM1 and PM3 levels of theory with a VSTO‐3G* basis set and in addition ab initio at the self‐consistent level of theory using a standard 6‐31G(d, p) basis set (Non‐SI units employed: kcal ≈ 4.184 kJ, Å = 10−10 m).© 1998 John Wiley & Sons, Inc.
