Abstract
The present invention relates to a method for producing an electrode material for a battery electrode, in particular for a lithium-ion battery, wherein said electrode material comprises nanostructured silicon carbide, comprising the steps of: a) providing a mixture including a silicon source, a carbon source and a dopant, wherein at least the silicon source and the carbon source are present in common in particles of a solid granulate; b) treating the mixture provided in step a) at a temperature in the range from ≥1400° C. to ≤2000° C., in particular in a range from ≥1650° C. to ≤1850° C., wherein step b) is carried out in a reactor that has a depositing surface the temperature of which relative to at least one other inner reactor surface is reduced. In summary, a method described above enables to combine a simple and cost-efficient production with a high cycle stability.
