  • Publication number: 20100259224
    Abstract: Electrolyte for an electrochemical battery cell that contains sulphur dioxide and a conductive salt. The electrolyte is a gel that is formed with to the involvement of a fluorosulphinate. The invention is also directed to a battery cell that contains such an electrolyte.
    Type: Application

    Inventors: Laurent Zinck, Guenther Hambitzer, Joachim Heitbaum, Christiane Ripp
  • Patent number: 7244530
    Abstract: Rechargeable battery cell operable at normal temperature, with an SO.sub.2 based electrolyte system, a negative electrode and a positive electrode, wherein one of the electrodes has an electronically conductive discharge element. An improved cycle stability and consequently a longer useful lifetime is achieved in that, as a reaction protection material to protect the discharge element against unwanted reactions with constituents of the SO.sub.2 based electrolyte system, at least a surface layer of the electronically conductive discharge element contains an alloy of chrome with another metal and/or a protective metal, selected from rhodium, tungsten, rhenium, tantalum, platinum, iridium, osmium or technetium in pure form, as an alloy or as a constituent of a compound and/or a carbide, nitride or phosphide of titanium, nickel, cobalt, molybdenum, iron, vanadium, zirconium or manganese.
    Type: Grant

    Inventors: Gunther Hambitzer, Christiane Ripp, Ingo Stassen, Laurent Zinck, Franziska Jager
  • Publication number: 20070065714
    Abstract: An electrochemical battery cell having a negative electrode, an electrolyte containing a conductive salt, and a positive electrode, the electrolyte being based on SO2 and the intermediate chamber between the positive electrode and the negative electrode being implemented such that active mass deposited on the negative electrode during the charging of the cell may come into contact with the positive electrode in such manner that locally delimited short-circuit reactions occur on its surface.
