Abstract: The present invention relates to the technical field of electrode materials, in particular to a silicon-carbon-based negative electrode material and a preparation method therefor. The silicon-carbon-based negative electrode material comprises a silicon material and a carbonaceous layer coating the surface of the silicon material, and the mass content of the silicon material is 30% to 50%. The silicon material is prepared by pickling a mixture of silicon oxide, a silicon-nickel alloy and a silicon-aluminum alloy, the silicon material has a porous structure, and the silicon-carbon-based negative electrode material has a porous structure. The silicon-carbon-based negative electrode material has a porous structure, which can alleviate the volume effect occurring during the process of charge and discharge, and reduce the pulverization and shedding of electroactive substances, thus improving the cycle stability of the lithium ion battery, and prolonging the service life and increasing the specific capacity of silicon-carbon-based negative electrode material. Coating the surface of a silicon material with a carbonaceous layer can effectively alleviate the problem of volume expansion of silicon materials. The silicon-carbon-based negative electrode material has a good cycle stability, a good conductivity and a high specific capacity, and also has good application prospects.
