  • Patent number: 12206099
    Abstract: A silicon-based anode material for secondary batteries, a preparation method thereof and a secondary battery are provided. The silicon-based anode material includes: an inner core including an Si particle and silicon oxide SiOx1, where 0<x1<2, a first shell layer including a compound of the general formula MySiOz (0<y?4, 0<z?5, and z?x1) and a C particle, wherein the first shell layer covers the inner core, and the contents of M and C in the first shell layer gradually increase from a side thereof close to the inner core to another side thereof far away from the inner core; and a second shell layer including a carbon film layer or a composite film layer formed by a carbon film layer and a conductive additive, the second shell layer covers the first shell layer. The first charge-discharge cycle capability of the silicon-based anode material is improved, and the manufacturing cost is reduced.

  • Patent number: 11658292
    Abstract: A silicon-based anode material, a preparation method thereof and a lithium ion battery are provided. The preparation method of the silicon-based anode material includes: passing a silicon substrate material through a vapor deposition gas to coat the surface of the silicon substrate material with a carbon deposition layer, the vapor deposition gas includes a first carbon source gas and a second carbon source gas, the volume percentage of the first carbon source gas and the second carbon source gas in the vapor deposition gas increases or decreases at different reaction stages for forming the carbon deposition layer. The side of the carbon deposited layer close to the silicon base material is more or less dense than the other side of the carbon deposited layer. The coating layer on the surface of the silicon-based anode material has a continuously changing junction, thereby greatly improving the cycling stability of the material.
