GALVANIC CELLS AND (PARTIALLY) LITHIATED LITHIUM BATTERY ANODES WITH INCREASED CAPACITY, AND METHOD FOR PRODUCING SYNTHETIC GRAPHITE INTERCALATION CONNECTIONS

The invention relates to a galvanic cell containing a cathode, a lithium-conductive electrolyte separator system, and a synthetic graphite-containing anode. In the manufacture of the cell (i.e. prior to the first charging cycle), the anode contains or consists of a (partially) lithiated graphite pow...

More Information
Summary:The invention relates to a galvanic cell containing a cathode, a lithium-conductive electrolyte separator system, and a synthetic graphite-containing anode. In the manufacture of the cell (i.e. prior to the first charging cycle), the anode contains or consists of a (partially) lithiated graphite powder which is produced from synthetic graphite and lithium powder in a non-electrochemical manner. The invention also relates to a method for (partially) lithiating synthetic graphite in an electroless manner. The invention is characterized in that the particulate synthetic graphite is (partially) lithiated in an electroless manner after mixing with particulate lithium metal powder and by means of a mixing and/or milling process, thereby forming Li graphite intercalates of the composition LiCx (mit x=6−600).
