  New inorganic ionic liquids possessing low melting temperatures and wide electrochemical windows: Ternary mixtures of alkali bis(fluorosulfonyl)amides

  摘要：

  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 5.4V 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 4.9V at 323 K with sodium metal deposition as the cathode limit reaction.

  The invention relates to a fluorination process for producing fluorinated compounds. The process consists in reacting a compound (I) corresponding to the formula 1 with an ionic fluoride of a monovalent cation. M represents H, an alkali metal, a quaternary phosphonium group or a quaternary ammonium group. Y represents SO 2 and m is 1, or else Y is PO and m is 2. Z represents CR 2 , N or P. R 1 represents an electron-withdrawing group which has a Hammet &sgr; P parameter of greater than 0.4. R 2 represents a carbonaceous and/or electron-withdrawing group. X represents a halogen other than a fluorine. The fluorinated compounds obtained are of use in particular as electrolytes in lithium batteries.

  Abstract A new route for the preparation of Li and Na salts of imido-bis(sulfuric acid) difluoride from KN(SO2F)2 as a starting material is described. KN(SO2F)2 was converted to Li and Na salts by metathetical reactions with lithium and sodium perchlorates in acetonitrile, while Rb and Cs salts were obtained from imido-bis(sulfuric acid) difluoride liberated from its K-salt. The crystal structure of

  摘要描述了一种以KN（SO2F）2为起始原料制备亚氨基双（硫酸）二氟化物锂盐和钠盐的新途径。通过与乙腈中的高氯酸锂和高氯酸钠发生易位反应，将KN（SO2F）2转化为Li和Na盐，而Rb和Cs盐则是从其K盐中释放出来的亚氨基-双（硫酸）二氟化物获得的。确定了双（氟硫磺酰基）酰亚胺锂LiN（SO2F）2（LISFI）的晶体结构。
