Metallic antimony with high capacity, abundant and a very appropriate reaction potential is considered as a promising anode material for LIBs. But poor cycle performance due to the huge volume expansion during cycling process seriously hinders its practical application. Here, Sb nanoparticles encapsulated into carbon nanosheets were prepared by a facile and scalable method. And the carbon nanosheets can effectively buffer the volume expansion and inhibit the aggregation of Sb nanoparticles during the lithiation/delithiation process. Finally, the as-prepared [email protected] nanosheets display superior rate capability (418 mAh g⁻¹ can be observed even at 5.0 A g⁻¹) and long cycle stability (449 mAh g⁻¹ can be maintained after 1000 cycle at 2.0 A g⁻¹). Furthermore, when coupled with LiFePO₄/C cathode, the [email protected]//LiFePO₄/C full cell also exhibits outstanding electrochemical performance.

具有高容量，丰富且非常合适的反应电势的金属锑被认为是有前途的LIB负极材料。但是由于循环过程中大量的膨胀而导致的循环性能差，严重阻碍了其实际应用。在此，通过简便且可扩展的方法来制备封装到碳纳米片中的锑纳米颗粒。并且碳纳米片可以有效地缓冲体积膨胀并在锂化/脱锂过程中抑制Sb纳米颗粒的聚集。最后，将所制备的[电子邮件保护]纳米片显示出优越的速率能力（418毫安克^-1可以观察到，即使在5.0 A G ^-1）和长周期稳定性（449毫安克^-1可以经过1000循环被维持在2.0克^-1）。此外，当与LiFePO ₄ / C阴极结合时，[受电子邮件保护] // LiFePO ₄ / C充满电池也表现出出色的电化学性能。
