  • A METHOD FOR PRODUCING A CARBON-SILICON COMPOSITE MATERIAL POWDER, AND A CARBON-SILICON COMPOSITE MATERIAL POWDER
    Publication number: 20230261174
    Abstract: The present disclosure relates to a method for producing a carbon-silicon composite material powder, comprising: providing a carbon-containing precursor, which is lignin; providing at least one silicon-containing active material; melt-mixing at least said carbon-containing precursor and said silicon-containing active material(s) to a melt-mixture; providing said melt-mixture in a non-fibrous form and cooling the melt- mixture to provide an isotropic intermediate composite material; subjecting said isotropic intermediate composite material to a thermal treatment, wherein said thermal treatment comprises a carbonization step to provide a carbon-silicon composite material, and subjecting said carbon-silicon composite material to pulverization to provide said carbon-silicon composite material powder.

  • PROCESS FOR PRODUCING THERMALLY STABILIZED LIGNIN
    Publication number: 20230235128
    Abstract: The present invention is directed to a process for the production of thermally stabilized agglomerated lignin, which avoids melting and/or significant foaming during subsequent thermal processing. The process comprises the steps of providing agglomerated lignin and heating the agglomerated lignin to obtain thermally stabilized agglomerated lignin. The thermally stabilized lignin can be further processed to a carbon enriched material.
