Negative electrode material, electrochemical apparatus, and electronic device |
| abstract |
This application provides a negative electrode material, an electrochemical apparatus, and an electronic apparatus. The negative electrode material provided in embodiments of this application includes a silicon-based material, or a silicon-based material and graphite. The silicon-based material includes a silicon oxide material and a carbon layer located on a surface of the silicon oxide material. A particle size distribution of the silicon-based material satisfies 1≤(D<sub>n</sub>99-D<sub>n</sub>10)/D<sub>n</sub>50≤4, D<sub>n</sub>10≥1 µm, and D<sub>n</sub>50≥3 µm. In the negative electrode material provided in the embodiments of this application, a number distribution of particle sizes of the silicon-based material can be controlled so that large and small particles are better matched, thereby improving cycling performance of an electrochemical apparatus. |
