Popis: | 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. |
