摘要
Recently, Li-ion batteries (LIBs) have attracted extensive attention owing to their wide applications in portable and flexible electronic devices. Such a huge market for LIBs has caused an ever-increasing demand for excellent mechanical flexibility, outstanding cycling life, and electrodes with superior rate capability. Herein, an anode of self-supported Fe3O4@C nanotubes grown on carbon fabric cloth (CFC) is designed rationally and fabricated through an in situ etching and deposition route combined with an annealing process. These carbon-coated nanotube structured Fe(3)O(4)arrays with large surface area and enough void space can not only moderate the volume variation during repeated Li(+)insertion/extraction, but also facilitate Li+/electrons transportation and electrolyte penetration. This novel structure endows the Fe3O4@C nanotube arrays stable cycle performance (a large reversible capacity of 900 mA h g(-1)up to 100 cycles at 0.5 A g(-1)) and outstanding rate capability (reversible capacities of 1030, 985, 908, and 755 mA h g(-1)at 0.15, 0.3, 0.75, and 1.5 A g(-1), respectively). Fe3O4@C nanotube arrays still achieve a capacity of 665 mA h g(-1)after 50 cycles at 0.1 A g(-1)in Fe3O4@C//LiCoO(2)full cells.
