Abstract Porous carbon originate d from Metal Organic Frameworks (MOFs) has attracted the attention of scholars because it inherits large specific surface area, plenty of pore structure, and adjustable morphology. Here, we reported N-doped porous carbon (N–P–C) with hierarchical pore structure obtained from nickel-based metal organic framework (note as Ni-ZIF). Due to its exceptional porosity, N-doped nature, and large surface area, the N–P–C exhibited superior electrochemical storage performance for lithium-ion batteries (LIBs). The resulting N–P–C material achieves excellent reversible capacity (725 mAh g−1 at 0.1 A g−1), cycling performance (570 mAh g−1 at 0.1 A g−1 after 200 cycles), and rate capability (239 mAh g−1 at a high current density of 2 A g−1). This facile strategy of fabrication of porous nitrogen-doped carbon anode materials provide a valid route to exploit cost-effective materials for LIBs.

锂离子电池用氮掺杂多孔碳的合成及电化学性能

摘要 源自金属有机骨架材料（MOFs）的多孔碳因其继承了大比表面积、丰富的孔结构和可调节的形貌而受到学者们的关注。在这里，我们报道了从镍基金属有机骨架（注为 Ni-ZIF）获得的具有分级孔结构的 N 掺杂多孔碳（N-P-C）。由于其特殊的孔隙率、N 掺杂性质和大表面积，N-P-C 表现出优异的锂离子电池（LIB）电化学存储性能。所得的 N-P-C 材料具有优异的可逆容量（725 mAh g-1，0.1 A g-1）、循环性能（200 次循环后 0.1 A g-1 时的 570 mAh g-1）和倍率性能（239 mAh g-1 在 2 A g-1 的高电流密度下）。
