Beschreibung
Zusammenfassung:The invention relates to a process for producing coated carbon particles, which comprises coating electrically conductive carbon particles with elemental doped or undoped silicon by chemical vapor deposition from at least one gaseous silane in an oxygen-free gas atmosphere in a reaction space, with the electrically conductive carbon particles being in continual motion during the vapor deposition, and also correspondingly coated carbon particles and their use in anode materials for lithium ion batteries.
