Abstract (en)
[origin: DE10128970A1] Rechargeable battery cell comprises a negative electrode; an electrolyte system; and a positive electrode. One of the electrodes has an electrically conducting deviating element with a surface layer made from a protective metal. The protective metal is selected from chromium, rhodium, tungsten, rhenium, tantalum, platinum, iridium, osmium or technetium in pure form as a component of an alloy or compound or carbide, nitride or phosphide of titanium, nickel, cobalt, molybdenum, iron, vanadium, zirconium or manganese. An Independent claim is also included for a process for the production of the battery cell. Preferred Features: The surface layer contains an oxide of chromium. The deviating element contains a core material made from copper, nickel, aluminum, carbon or high grade steel. At least one component of the surface layer is applied in the gas phase and one is applied galvanically. The electrolyte is based on sulfur dioxide (SO2).
