Double carbon coated Fe P composite(Fe P@NC@r GO)was in situ fabricated via the phosphorization process of the as-prepared Prussian blue@graphene oxide(PB@GO)precursor.The Fe P nanocrystals were successfully embedded in the nitrogen-doped porous carbon matrix.When used as the anode for lithium ion batteries(LIBs),the Fe P@NC@r GO anode shows superior lithium storage properties,delivering a high specific capacity of 830 m A h g^(-1)after 100 cycles at 100 m A g^(-1)and excellent rate capability of 359 m A h g^(-1)at 5 A g^(-1).The outstanding performance mainly ascribes to the synergistic effect of the double carbon coating and porous structure design.The introduction of porous carbon and graphene coating on Fe P nanoparticles greatly enhance the electronic conductivity of the active material and well accommodates the large volume variation of Fe P during the cycling process.
