Product Features

^{1）Enhanced conductivity: The incorporation of nitrogen atoms increases the charge density of hard carbon materials, forming an n-type semiconductor that improves their electrical conductivity.}

^{2）Enhancing sodium/lithium storage sites: Nitrogen doping can provide more active sites for sodium/lithium storage, facilitating rapid ion diffusion between carbon layers and improving the material's sodium/lithium storage capacity.}

^{3）Optimizing surface structure: Nitrogen doping reduces defects and oxygen-containing functional groups on the hard carbon surface, inhibits electrolyte decomposition, and improves the material's initial Coulombic efficiency (ICE) and cycling stability.}

^{4）The interlayer spacing is increased by nitrogen doping, which is beneficial to the intercalation and deintercalation of sodium and lithium ions, and improves the rate performance of the material.}

Application Fields

^{1）Sodium-ion battery anode materials: Nitrogen-doped hard carbon materials are considered ideal choices for sodium-ion battery anodes due to their high specific capacity, excellent rate performance, and cycling stability. For instance, nitrogen-doped hard carbon materials prepared from potato starch as a precursor exhibit outstanding electrochemical performance in sodium-ion batteries.}

^{2）Lithium-ion battery anode materials: Nitrogen-doped hard carbon materials can also be used as anode materials for lithium-ion batteries. Their unique structure and properties contribute to improving the rate performance and cycling stability of lithium-ion batteries. For instance, hard carbon materials derived from carbonized vegetable vines exhibit high discharge capacity when employed as lithium-ion battery anodes.}

^{3）Catalysis: Nitrogen-doped carbon materials have garnered significant attention in catalysis due to their unique electronic and chemical properties. Nitrogen doping introduces defect sites and nitrogen species, enhancing the physicochemical properties, acidity/alkalinity, and wettability of catalysts. Additionally, it facilitates interactions with active species, thereby improving catalytic performance.}
