Facile Preparation of Fe3O4/Carbon Nanocomposite With High Lithium Storage Capacity

In the present work, Fe3O4/carbon nanocomposite was prepared using metal organic framework as a precursor. Meanwhile, the electrochemical performance of the Fe3O4/carbon nanocomposite, as an anode material, was evaluated by galvanostatic discharge-charge tests. The experimental results indicate that the as-prepared sample is a porous aggregation of Fe3O4 nanoparticles interconnected with amorphorous carbon layer, and the mean diameter of Fe3O4 nanoparticles is approximately 30 nm. Moreover, it is also observed that the Fe3O4/carbon nanocomposite possesses a high initial discharge capacity of 1586 mA h g−1.
