SILICON-CARBON ANODE MATERIAL BASED ON ORGANOSILICON-DERIVED WASTE SILICON POWDER, AND PREPARATION METHOD THEREFOR AND USE THEREOF

The preparation method for a silicon-carbon anode material based on organosilicon-derived waste silicon powder includes: performing rapid annealing treatment on organosilicon-derived waste silicon powder, and mixing the rapidly annealed waste silicon powder with an acid solution for acid leaching to obtain modified waste silicon powder; performing mechanical grinding on the modified waste silicon powder to obtain a modified waste silicon powder abrasive; mixing the modified waste silicon powder abrasive with an organic carbon source and a solvent to obtain a precursor solution, and performing spray granulation on the precursor solution to obtain silicon-carbon microspheres; and introducing a carbon-deposition precursor source, and performing carbon deposition on the silicon-carbon microspheres to obtain a silicon-carbon anode material.
