Abstract: A method includes etching metallic impurities from an aluminosilicate mineral in a liquid acid etchant and separating solids including silica from the liquid acid etchant. The method further includes reducing the silica in the separated solids to silicon using a solid reducing agent resulting in a silicon-residual silica composite, removing aluminum chloride from the silicon-residual silica composite, dissolving oxides of the solid reducing agent in an acid solution, and separating silicon-residual silica solids remaining in the acid solution from the acid solution. The separated silicon-residual silica solids are dried to produce a clay mineral-derived silicon product.

Abstract: 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).
