titleOfInvention | Silicon-carbon composite negative electrode material, and preparation method and application thereof |
abstract | A silicon-carbon composite negative electrode material, a preparation method and application. The invention belongs to the technical field of lithium ion battery cathode materials, and particularly discloses a nitrogen-rich graphite nanosheet/nano-silicon composite material which comprises a nitrogen-rich graphite nanosheet with a two-dimensional structure and nano-silicon particles uniformly compounded on the surface of the nitrogen-rich graphite nanosheet in situ. In addition, the invention also provides the preparation of the material, which is obtained by taking a CN source as a precursor, carrying out secondary treatment in an oxygen-containing atmosphere, then loading silicon, mixing with a metal reducing agent and compound salt, and carrying out secondary gradient reduction in an inert atmosphere. The research of the invention finds that the structural stability can be effectively improved and the electrochemical performance of the material can be improved due to the synergistic effect between the components and the morphological characteristics of the material. |
