A novel Ag@nitrogen-doped porous carbon (Ag-NPC) composite was synthesized via a facile hydrothermal method and applied as an anode material in lithium-ion batteries (LIBs). Using this method, Ag nanoparticles (Ag NPs) were embedded in NPC through thermal decomposition of AgNO₃ in the pores of NPC. The reversible capacity of Ag-NPC remained at 852 mAh g⁻¹ after 200 cycles at a current density of 0.1 A g⁻¹, showing its remarkable cycling stability. The enhancement of the electrochemical properties such as cycling performance, reversible capacity and rate performance of Ag-NPC compared to the NPC contributed to the synergistic effects between Ag NPs and NPC.

具有高电化学性能的新型Ag @氮掺杂多孔碳复合材料作为锂离子电池的负极材料

通过一种简便的水热法合成了一种新型的Ag掺杂氮的多孔碳（Ag-NPC）复合材料，并将其作为锂离子电池（LIBs）的负极材料。使用这种方法，通过AgNO ₃在NPC孔中的热分解，将Ag纳米颗粒（Ag NPs）嵌入到NPC中。的Ag-NPC的可逆容量保持在852毫安克^-1处的0.1 A g的电流密度200次循环后^-1，显示出其显着的循环稳定性。与NPC相比，Ag-NPC的电化学性能（例如循环性能，可逆容量和倍率性能）的增强有助于Ag NP和NPC之间的协同作用。
