Fluorinated sulfonamide compounds, useful as non-flammable solvents in electrolytes for electrochemical cells, e.g. lithium batteries for mobile telephones

摘要

Fluorinated sulfonamides are of specified formula (I). Compound of formula (I) is shown below. X = H, F, Cl, CnF2n+1, CnF2n-1 or (SO2)kN(CR<1>R<2>R<3>)2; Y, Z = H, F or Cl; R<1>-R<3> = H and/or alkyl, fluoroalkyl or cycloalkyl; m = 0-9 (not zero if X = H); n = 1-9; k = 0 if m is 0, or 1 if m = 1-9. Independent claims are also included for the following: (a) a method for the production of (I) by reacting partly- or per-fluorinated alkylsulfonyl fluorides with dimethylamine in organic solvents; (b) a method for the production of (I) by reacting halo-sulfonamides with ordinary fluorinating agents in organic solvents; (c) electrolytes containing (I); and (d) electrochemical cells (especially lithium batteries and super condensers) essentially comprising cathode, anode, separator and an electrolyte containing (I);
