Iron monophosphide (FeP) anode, with high theoretical capacity and available resources applied in advanced lithium ion batteries, is faced with the challenge of dramatic volume expansion during cycling. Here, a novel 3D graphene framework scaffolded FeP nanoparticles composite was designed and fabricated via a facial three-step method. 3D FeP-rGO anode delivers an unprecedented rate performance (458 mA h g(-1) at 10 A g(-1)) and excellent long cycling performance (448 mA h g(-1) at the high current density of 3 A g(-1) over 500 cycles). More impressively, the full cell consisting of 3D FeP-rGO anode and LiFePO4 cathode shows a stable Li+ storage performance with a high capacity retention of 97% (373 mA h g(-1)) at 0.5 A g(-1) after 120 cycles. The excellent electrochemical performance can be ascribed to the special hierarchical 3D graphene framework of composite that can provide abundant channels to facilitate the rapid Li+ diffusion and accommodate the volume change during cycling.
