摘要

We report the synthesis of a novel shuttle-like Fe3O4-Co3O4 self-assembling architecture through a facile hydrothermal method. The composite manifests quite excellent electrochemical performance as anodes of Li-ion batteries. It delivers a high reversible capacity of similar to 1013 mA h g(-1) at 100 mA g(-1) after 100 cycles (similar to 1246 mA h g(-1) at 0.5 A g(-1), 864 mA h g(-1) at 1 A g(-1) and 625 mA h g(-1) at 2 A g(-1) after 50 cycles). The rate performance is also outstanding with a reversible capacity of 660 mA h g(-1) even at 5 A g(-1) and a capacity retention of 94% after 78 cycles. The synergetic effect of Co3O4 and Fe3O4, as well as the unique self-assembling architecture, may be responsible for the large enhanced electrochemical performance.
