N,S-codoped porous carbon nanosheets decorated with Fe3C nanoparticles as high-performance anode materials for lithium ion hybrid supercapacitors
文献摘要：
The practical applications of carbon anode for lithium-ion batteries(LIBs)are largely obstructed by their moderate rate capability and cyclic stability.Herein,we report a N,S-codoped porous carbon nanosheet(NSC)decorated with Fe3C nanoparticles(Fe3C/NSC)by a one-pot pyrolysis process.The high surface area and abundant defects of NSC can not only promote electrons and ions transfer,but also induce high pseudocapacitive contribution.More importantly,the synergistic catalysis effect of Fe-Nx and Fe3C can catalyze the reversible conversion of some solid electrolyte interface(SEI)components to offer excess capacity during cycling.As expected,the Fe3C-NSC anode delivers a discharge capacity of750 mAh·g-1 under a current density of 0.5 A·g-1 through 500 cycles and retains a dis-charge capacity of 366 mAh·g-1 at 4 A·g-1 after 1600 cycles,respectively.Most importantly,the lithium-ion capacitors based on Fe3C/NSC anode demonstrate a high energy density of 249.5 Wh·kg-1 at 560 W·kg-1.
