二维（2D）锑烯（Sb）由于其理论容量（660 mAh g−1）而被认为是锂离子电池的有前途的阳极候选物。制备六方Sb纳米片（H-SbNs）是解决急剧体积膨胀和粉碎问题的有效策略。在这里，我们提出了一种简单的方法，通过静电纺丝与热退火过程在碳纤维表面制备少层H-SbNs。当作为锂存储的阳极进行评估时，H-SbN电极具有高倍率性能和优异的循环稳定性。电化学分析表明，H-SbN电极显示出主要受扩散控制的电容贡献和优异的锂离子和电子传输。我们的研究结果表明，2D材料是上级用作电化学锂存储的锑基阳极。
Two‐dimensional (2D) antimonene (Sb) is regarded as a promising anode candidate for lithium‐ion batteries owing to its theoretical capacity (660 mAh g−1). Preparing hexagonal Sb nanosheets (H‐SbNs) has been addressed an effective strategy to resolve the drastic volume expansion and the pulverization issues. Here, we present a facile method to prepare the few‐layer H‐SbNs on the surface of carbon fibers via the electrospinning with a thermal annealing process. When evaluated as an anode for lithium storage, the H‐SbN electrode delivers a high rate performance and excellent cycling stability. Electrochemical analysis reveals that the H‐SbN electrode displays the mainly diffusion‐controlled capacitive contributions and excellent lithium‐ion and electron transport. Our findings demonstrate that 2D materials are superior to use as the Sb‐based anodes for electrochemical lithium storage.
