英文摘要

A new kind of nitrogen-phosphorus co-doped porous carbon (NPPC) material was prepared by using ionic liquids as a dual functional agent and KCl and ZnCl(2)as a salt template. Scanning electron microscopy and transmission electron microscopy images demonstrated that the NPPC material has a uniform porous structure with a high specific surface area of 589.97 m(2)g(-1). When the NPPC material used as anode materials for lithium-ion batteries, thanks to its good pore structure (contain rich mesoporous and macroporous) and successful doping of nitrogen and phosphorus (9.12 and 0.28 at.%, respectively), its initial discharge capacity is up to 685 mAh g(-1)at a current density of 0.1 A g(-1). After 50 cycles, reversible capacity of NPPC stays around 715 mAh g(-1)and the coulomb efficiency remained above 97%. After 400 cycles at the current density of 2 A g(-1), the capacity can still maintain at 394.1 mAh g(-1). All results show that the NPPC material has excellent electrochemical properties that can be viewed as a promising candidate for anode materials in lithium-ion batteries.
