Amorphous carbon has been studied in anode electrode materials of lithium ion batteries (LIBs) due to its rich resources and adjustable structure. However, due to its low conductivity, it shows poor rate performance. In this work, amorphous nitrogen doped porous carbon (NDPC) was synthesized by salt template method using ionic liquid (C₁₀H₁₅N₅) as sources of carbon and nitrogen. The structure characterization shows that there is an interaction between the introduction of nitrogen atoms and porous structure: nitrogen doping can promote charge transfer, and porous carbon structure can reduce the diffusion path of lithium ions. Therefore, the NDPC shows excellent lithium ion diffusion ability and good electronic conductivity. When NDPC is applied to the anode material of LIBs, it shows a superior lithium ion storage performance of 412 mA h g⁻¹ after 200 cycles at a current density of 1860 mA g⁻¹. The study provides favorable conditions for the development of carbon anode materials with in situ heteroatom doping and porous structure.

无定形碳由于其丰富的资源和可调节的结构而在锂离子电池（LIBs）负极材料中得到了研究。然而，由于其低电导率，其倍率性能较差。在这项工作中，采用盐模板法使用离子液体（C ₁₀ H ₁₅ N ₅) 作为碳源和氮源。结构表征表明，氮原子的引入与多孔结构之间存在相互作用：氮掺杂可以促进电荷转移，多孔碳结构可以减少锂离子的扩散路径。因此，NDPC表现出优异的锂离子扩散能力和良好的电子导电性。当NDPC应用于锂离子电池负极材料时，在1860 mA g ^-1的电流密度下循环200次后，表现出412 mA h g ^-1的优异锂离子存储性能。该研究为开发具有原位杂原子掺杂和多孔结构的碳负极材料提供了有利条件。
