Abstract: The present invention is directed to a method for producing an agglomerated lignin-silicon composite material. The method involves the steps of mixing lignin in powder form, at least one silicon-containing active material in powder form and optionally at least one additive; compacting the mixture; and crushing the compacted composite material to obtain an agglomerated lignin-silicon composite material. The invention is also directed to a granular carbon-silicon composite material obtained by heat treatment of the agglomerated lignin-silicon composite material.
