Abstract

Zinc-ion batteries (ZIBs) have become a highly desirable energy storage technology due to their significant advantages, such as low cost and high safety; however, the limitation of cathode materials has become a major factor restricting the development of ZIBs. Here, molybdenum diselenide (MoSe2) nanoflakes were investigated for the first time as a novel cathode for ZIBs. The unique two-dimensional (2D) layered structure of MoSe2 provides convenient channels and multiple active sites for zinc (Zn) ion diffusion. MoSe2 showed a specific capacity of 30.1 mA h/g at 0.1 A/g as well as almost no capacity decay at 1.0 A/g after 1500 cycles. Further, the Zn–MoSe2 coin cell successfully excited a light-emitting diode, showing good application prospects. Moreover, there was almost no aging of the battery after cycling, thus indicating satisfactory application potential. This work broadens the application of 2D materials in ZIBs.

用于锌离子存储的 MoSe2 纳米薄片

锌离子电池（ZIB）具有成本低、安全性高等显著优势，已成为一种非常理想的储能技术；然而，阴极材料的局限性已成为制约锌离子电池发展的一个主要因素。本文首次将二硒化钼（MoSe2）纳米片作为新型 ZIB 阴极材料进行了研究。MoSe2 独特的二维（2D）层状结构为锌（Zn）离子扩散提供了便捷的通道和多个活性位点。MoSe2 在 0.1 A/g 条件下的比容量为 30.1 mA h/g，在 1.0 A/g 条件下循环 1500 次后容量几乎没有衰减。此外，Zn-MoSe2 纽扣电池还成功激发了一个发光二极管，显示出良好的应用前景。此外，电池在循环后几乎没有老化，这表明其具有令人满意的应用潜力。这项研究拓宽了二维材料在 ZIB 中的应用。
