  • Amines or salts thereof and methods of preparing same
    Patent number: 6642404
    Abstract: The invention relates to a first compound which is a first amine or a first salt thereof, and to a second compound which is a second amine or a second salt thereof. The first compound has a fluorocarbon sulfonic acid ester group and is represented by a general formula of M[Rf1OSO2NSO2ORf2]n wherein Rf1 and Rf2 represent the same or different fluorine-containing monovalent organic groups. The first amine is prepared by reacting bis(chlorosulfonyl)amine with a fluoroalcohol represented by a general formula of Rf3OH wherein Rf3 represents the same of different groups which are identical with Rf1 and Rf2. The second compound has a fluorocarbon sulfonic acid ester group and is represented by a general formula of —[M[N—SO2ORf4OSO2]n]m— wherein Rf4 represents a fluorine-containing bivalent organic group.

  • Ion conductive material and electrochemical device comprising the same
    Patent number: 5902698
    Abstract: An ion conductive material containing a compound which comprises a resonance structure group which contains an atom of the Vb group in the Periodic Table serving as an anionic site and is bonded to an electron attractive organic group through an atom of the VIb group in the Periodic Table, and a counter ion selected from the group consisting of metal ions and a hydrogen ion. This material is useful as an electrolyte of a cell since it is excellent in high voltage stability.
