  • High energy electrochemical current source
    Patent number: 4158722
    Abstract: In a galvanic element having a negative metal electrode, and non-aqueous electrolyte, the electrochemically reducible component of the positive electrode mass is a chromium oxide of the formula CrO.sub.x, where x lies in the range between 2 and 2.9.
    Type: Grant
    Filed: May 31, 1978
    Date of Patent: June 19, 1979
    Assignee: Varta Batterie Aktiengesellschaft
    Inventors: Helmut Lauck, Franz-Josef Kruger
  • Galvanic element with negative light metal electrode and non-aqueous organic electrolyte
    Patent number: 4156058
    Abstract: A galvanic element with negative light metal electrode and non-aqueous electrolyte, and having active material which is an organic sulfohalogenide.
    Type: Grant
    Filed: May 18, 1978
    Date of Patent: May 22, 1979
    Assignee: Varta Batterie A.G.
    Inventors: Franz J. Kruger, Helmut Lauck
  • Light metal galvanic element
    Patent number: 4085259
    Abstract: In a cell which uses a light metal negative electrode, the positive electrode mass has an electrochemically reducible component which is mainly Bi.sub.2 O.sub.3 and the electrolyte is a conductive salt dissolved in a mixture composed mainly of propylene carbonate and dimethoxyethane.
    Type: Grant
    Filed: March 23, 1976
    Date of Patent: April 18, 1978
    Assignee: Varta Batterie Aktiengesellschaft
    Inventor: Helmut Lauck
  • Manufacture of galvanic elements having lithium or calcium electrodes
    Patent number: 4069375
    Abstract: Lithium- or calcium-electrode elements are manufactured in air by first pretreating the electrode foil with a gas which reacts with the metal foil surface to form a temporary protective layer.
    Type: Grant
    Filed: September 10, 1976
    Date of Patent: January 17, 1978
    Assignee: Varta Batterie Aktiengesellschaft
    Inventor: Helmut Lauck
  • Galvanic element with a negative electrode of light metal, a non-aqueous electrolyte and a positive electrode
    Patent number: 4060675
    Abstract: Galvanic element with a negative electrode of a light metal, a non-aqueous electrolyte and a positive electrode containing arsenites, particularly silver and mercury arsenites, as the electrochemical reducible part of the electrode mass. The use of arsenites exhibit an especially high energy density and a very constant discharge potential during operation.
