摘要： A process of producing active material for an electrode of an electrochemical cell includes a buildup step A in which a pulverulent composite composed of lithium-intercalating carbon particles as component 1, silicon particles as component 2 and a polymer that can be pyrolyzed to form amorphous carbon as component 3 is formed, and a pyrolysis step B in which the composite is heat treated in the absence of atmospheric oxygen at a temperature at which the pyrolyzable polymer decomposes to form amorphous carbon, wherein the lithium-intercalating carbon particles are transferred in the buildup step A into a fluidized-bed reactor and coated with a shell composed of the polymer and the silicon particles to effect direct formation of the pulverulent composite, and the polymer that can be pyrolyzed to form amorphous carbon or a corresponding polymer precursor and/or the silicon particles are fed into the fluidized-bed-reactor as solution or suspension.
