METHOD FOR PRODUCING A LITHIUM-CONTAINING ELECTRODE, AND ELECTROCHEMICAL CELL

A method for producing a lithium-containing electrode for a lithium-ion containing accumulator is provided, including:—producing a metal foil;—coating a surface of the metal foil with a graphite layer;—introducing the metal foil into an electrochemical cell as a first electrode, which is used as a cathode;—introducing a second, lithium-containing electrode into the cell used as an anode;—wherein lithium compounds are introduced into the second electrode, the lithium compounds originating from thermally decomposed electrode material of a lithium-ion accumulator;—introducing a non-aqueous electrolyte into the cell;—closing the cell under inert conditions;—applying an electrical current to the electrodes of the cell such that lithium ions migrate from the lithium-containing anode to the cathode in the form of the metal foil provided with the graphite layer, through the non-aqueous electrolyte; and—the surface of the metal foil is intercalated to form lithium ions.
