Abstract

The present disclosure relates to a silicon-carbon composite anode material, which has a core-shell structure including a core layer of nano-silicon and a shell layer at least partially or fully coating the core layer of nano-silicon, the shell layer includes at least one layer of nitrogen-doped graphite. Sizes of the core-shell structure are in a range of 5 µm to 10 µm, and the nitrogen content of the nitrogen-doped graphite layer is less than or equal to 10%. Additionally, the present disclosure provides a preparation method for the silicon-carbon composite anode material and a secondary battery including the silicon-carbon composite anode material.
