The unfavorable rate capacities and cycling property are insurmountable problems for application of pure MoS2 anode in Li-ion batteries. In this regard, a brief methodology used in the synthesis of AgNWs@MoS2 is discussed. Emphasis is placed on the construction of a nanocomposite anode by which the cycling behavior and rate capability of MoS2 can be improved. As the 1D skeletons of Ag nanowires constitute fast conductive pathways and prevent volume expansion of pure MoS2 as charge/discharge process, enhancing the Li+ diffusion coefficient in electrode. The experimental results reveal interesting examples of AgNWs@MoS2 anode of admirable rate property and promising long-cycling appearance (310 mAh g−1 at 1 A g−1 after 1000 cycles). The scope of this research lies in providing a type of excellent anode material in Li-ion batteries.

在 Ag 纳米线上构建类似蛇皮的 MoS2 作为锂离子电池的增强扩散动力学阳极

不利的倍率容量和循环性能是纯MoS 2负极在锂离子电池中应用不可克服的问题。在这方面,讨论了用于合成 AgNWs@MoS 2的简要方法。重点放在纳米复合阳极的构建上,通过该阳极可以改善MoS 2的循环行为和倍率性能。由于Ag纳米线的一维骨架构成了快速导电通路,并防止纯MoS 2在充放电过程中发生体积膨胀,从而提高了电极中的Li +扩散系数。实验结果揭示了 AgNWs@MoS 2的有趣例子阳极具有令人赞叹的倍率特性和有希望的长循环外观(1000 次循环后在 1 A g -1时为 310 mAh g -1 )。这项研究的范围在于为锂离子电池提供一种优良的负极材料。
