Document Type and Number:
WIPO Patent Application WO/2024/000823
Kind Code:
A1
Abstract:
The embodiments of the present invention relate to a multi-hierarchical composite material prepared at an ultra-high temperature, and a preparation method therefor and the use thereof. The multi-hierarchical composite material comprises: a carbon matrix and a nano-silicon-based composite material, wherein the nano-silicon-based composite material is prepared by means of a thermal plasma process, which specifically comprises: bombarding and ionizing a micron-scale silicon powder and one or more substances containing a doping element in a high-frequency plasma processing device to form a plasma gas having a temperature of 5000 K or more, and then cooling same and depositing same into a core, thereby obtaining a nanoscale silicon-based composite material with doping elements uniformly embedded and distributed at an atomic scale; the doping element comprises at least one of C, N, B, P, S, Mg, Ca, Al, Zn, Mn, Ni or Ti; the carbon matrix is a porous carbon material; and the nano-silicon-based composite material is deposited in the porous structure of the carbon matrix.
