  • Patent number: 10892477
    Abstract: The present invention relates to a porous silicon-silicon oxide-carbon composite comprising a silicon oxide-carbon structure and silicon particles, wherein the silicon oxide-carbon structure comprises a plurality of micropores, and the silicon particles are uniformly distributed in the silicon oxide-carbon structure. The porous silicon-silicon oxide-carbon composite of the present invention shows decreased volume expansion due to the intercalation of lithium ions and improved electric conductivity, and has a porous structure. Accordingly, an electrolyte easily penetrates into the porous structure, and output properties may be improved. When the composite is included in a negative electrode active material, the performance of a lithium secondary battery may be further improved.
