N-doped Si/C COMPOSITE AND MANUFACTURING METHOD THEREOF

A manufacturing method of a N-doped Si/C composite, comprising:

• mixing the nitrogen-containing precursor, the carbon source, and the silicon source to provide a mixture;
• and
• sintering the mixture in an inert atmosphere to obtain the N-doped Si/C composite,
• wherein the N-doped Si/C composite comprises a plurality of carbon-silicon particles,
• each of the plurality of carbon-silicon particles comprises one or more silicon particles and a carbon coating layer covering the one or more silicon particles, wherein a plurality of first nitrogen atoms is distributed in the one or more silicon particles of each of the carbon-silicon particles via a silicon-nitrogen bond, and a plurality of second nitrogen atoms is distributed in the carbon coating layer of each of the carbon-silicon particles via a nitrogen-carbon bond.
