| titleOfInvention | A kind of micron silicon carbon composite material for negative electrode of lithium ion battery and preparation method thereof |
| abstract | The invention belongs to the field of lithium ion battery materials, and discloses a micron silicon-carbon composite lithium ion battery negative electrode material and a preparation method. The preparation method includes: ball-milling micron silicon and conductive carbon to obtain precursor A; adding the carbon source precursor to a solvent to obtain carbon source solution B; (2) adding precursor A to carbon source solution B, Alternately stirring and sonicating to obtain uniformly mixed slurry C; (3) under stirring, adding slurry C to an aqueous solution of surfactant to shape, filtering and drying to obtain precursor D; (4) mixing precursor D The micron silicon-carbon composite material is obtained after high-temperature carbonization treatment in a protective atmosphere. The invention uses micron-scale silicon-based materials as raw materials, and uses ball milling and surfactant-assisted methods to form a core-shell structure; the material has a stable structure, and the external carbon shell can effectively alleviate the volume change of silicon and maintain the electrode structure stability. The invention has low cost and simple preparation method, which is favorable for large-scale production. |
