  • Patent number: 9972836
    Abstract: An SiOx/Si/C composite material, includes SiOx/Si composite particles and a carbon coating layer coated on the SiOx/Si composite particles. The SiOx/Si composite particles include nano-silicon crystallites embedded in an SiOx (0<x?2) amorphous matrix phase. The SiOx/Si composite particles have an Si:O molar ratio of 5:1-1.1:1, preferably 2:1-1.2:1. A process for producing an SiOx/Si/C composite material, includes a) milling SiO powder together with a metal reductant in a molar ratio of 125:1-10:1, preferably 2:11-5:1, b) totally removing the oxidation product of the metal reductant to obtain SiOx/Si composite particles, and c) coating the SiOx/Si composite particles with carbon to obtain the SiOx/Si/C composite material.
