摘要

二维材料因其化学稳定性、高导电性和大比表面积而适合于储能应用。本文采用化学剥离法制备了二硫化钨(WS2)纳米片，并将其与氧化镍(NiO)纳米片结合，作为储能工作电极。单独WS2电极的电容约为21.87 mF⸳cm-2，加入NiO纳米颗粒后，其电容可提高到64.58 mF⸳cm-2。氧化还原反应的发生对最终电容的增加起着重要的作用。此外，在5000次充放电循环后，该混合动力车的初始电容保持在93%，表明其性能稳定可靠。

Tungsten disulfide-nickel oxide hybrids as high-performance supercapacitors

Two-dimensional materials are suitable for energy storage applications due to their chemical stability, high electrical conductivity and large specific surface area. In this work, tungsten disulfide (WS2) nanosheets were synthesized by chemical exfoliation method and combined with nickel oxide (NiO) nanoparticles to be used as a working electrode for storing energy. The WS2 electrode alone shows a capacitance of about 21.87 mF⸳cm-2, which is improved up to 64.58 mF⸳cm-2 by adding NiO nanoparticles. The occurrence of redox reactions plays an important role in increasing the final capacitance. Moreover, the proposed hybrid maintains 93% of its initial capacitance after 5000 charge-discharge cycles, which indicates its stable and reliable performance.
