| titleOfInvention | Preparation method, product and application of nitrogen-doped hard carbon material |
| abstract | The invention discloses a preparation method of nitrogen-doped hard carbon material, its product and application. The preparation method comprises the following steps: using glucose as a raw material, through hydrothermal reaction pretreatment to cause intermolecular dehydration to cause cross-linking reaction to form carbon microspheres; The pretreated carbon microspheres are mixed with a nitrogen-containing precursor, and finally calcined at a high temperature under an inert gas to rearrange the atoms to obtain a nitrogen-doped hard carbon material. The prepared material improves the storage of hard carbon. The performance of sodium enhances its conductivity, but also regulates its microstructure and increases active sites, thereby further improving the specific capacity, rate performance and cycle life of hard carbon in sodium-ion batteries; ization is important. |
