A salt-template approach is used to construct hybrid materials composed of Fe3O4 nanoparticles embedded in hierarchical porous carbon. The hybrid materials show excellent performance and have potential application as anode materials in lithium-ion batteries.
Herein, we reported a salt-template approach for the construction of hybrid materials composed of Fe3O4 nanoparticles embedded in hierarchical porous carbon. Benefiting from the combined effect of sufficient space to alleviate the volume expansion of Fe3O4 and the good electronic conductivity of three dimensional inter-connected framework, the hybrid materials deliver excellent performance. HPCs/Fe3O4 -2 anode displays a high reversible capacity of 1018.4 mAh g-1 after 250 cycles at 0.2 A g-1, and an excellent cycling-life stability of 415.4 mAh g(-1) after 1000 cycles at a high current density of 5 A g-1, suggesting the potential application in LIBs anode. Such an effective and simple approach to construct carbon-based hybrid materials can be further extended to fabricate other anode and cathode materials with excellent performance.
