| titleOfInvention | Composite silicon negative electrode material, preparation method and use |
| abstract | The present invention includes nanosilicon, a surface of nanosilicon, a nanocomposite layer, and a conductive carbon layer uniformly coated on the outside of the nanocomposite layer, wherein the nanocomposite layer is made of silicon oxide and metal alloy. A composite silicon negative electrode material is provided. In the composite silicon negative electrode material having a three-layer structure, the nanocomposite layer composed of silicon oxide and a metal alloy coated on the surface of the silicon oxide effectively reduces the volume expansion of the nanosilicon, and the silicon material Maintaining high conductivity characteristics, improving lithium ion mobility, avoiding direct contact between silicon negative electrode and electrolyte, and forming a strong SEI film on the surface of composite silicon negative electrode material, material cycle Greatly improve performance. The composite silicon negative electrode material has high capacity, long cycle life and high conductivity characteristics. The process for preparing the silicon negative electrode material is simple and easy to control, and is suitable for industrial production. [Selection] Figure 1 |
