4. ConclusionsIn summary, a unique surface-induced polymerization method was determined to obtain the hierarchically porous carbon nanosheets with hybrid homogenous N, P functionalization. In the case, the obtained NPHC delivered a high discharge capacity of 763.4mAh g−1at a current density of 100mAg−1, a superior rate capability with 146.6mAh g−1 at 8000mAg−1 and the high capacity retention of 83% after 1000 cycles at 2000mAg−1. Such excellent reaction kinetics could be attributed to the remarkable contribution of surface capacitance, which might be resulted from good electrical conductivity and short diffusion length of N, P hybrid functionalized hierarchically porous carbon nanosheets. XPS spectrum confirmed that the surface-induced method could greatly increase the surface nitrogen, oxygen, phosphorus functionalities and defects of nanosheets, thus improving the electrochemical performance as a lithium ion battery anode.
