　　Sodium-ion batteries have recently gained a lot of interest due to its low cost and widely applications.However,the main challenge is to develop an anode material with superior high-rate capability and long-term cycling stability.Here,we initiatively applied Ni2P nanoparticles in-situ grown on hierarchical porous graphitic carbon(HPGC)that synthesized by chemical vapor deposition method as anode material of sodium ion batteries.The Ni2P/HPGC composite shows a high reversible specific capacity of 489 mAh g-1 at the current density of 100 mA g-1 and a good long-term cycle stability for 2000 cycles,which exhibits an excellent rate performance and cycling stability.
