英文摘要 | Nitrogen-sulfur co-doped porous carbon (NSPC) were prepared by using ionic liquids as both nitrogen and sulfur source. The as-obtained NSPC exhibits open pore structure with thin carbon walls and nitrogen (2.32wt%) and sulfur (0.91wt%) doping. When used as lithium-ion batteries (LIBs), NSPC shows a high reversible capacity of 821mAhg(-1) at 0.1Ag(-1) after 50 cycles. Even after 1000 cycles, the NSPC exhibits a stable reversible capacity of 533mAhg(-1) at current density of 1.5Ag(-1). The excellent electrochemical performance of NSPC is attributed to two points: (1) interconnected three-dimensional pore structure; (2) Nitrogen and sulfur doping and the synergic effect of dual-doping heteroatoms. This work provides new ideas for the development of new anode materials for LIBs. |
