Abstract
A method is described for producing silicon particles, in particular for an anode material of a lithium cell. In order to improve the cycle stability of lithium cells and to minimize losses in capacitance, in particular, microorganisms are dispersed in at least one solvent in a method step a), the solvent including at least one silicon compound. In a method step b), the at least one solvent is then removed, and a residue remains. In method step c), the residue is then heated under a reducing atmosphere. In addition, the invention relates to corresponding silicon particles, and to a corresponding anode material including silicon particles, and to a lithium cell provided with such.
