摘要:
以泡沫镍为自支撑基底,采用两步水热法在泡沫镍(NF)上合成FeCo2S4自支撑电极材料(FeCo2S4/NF)。通过扫描电子显微镜(SEM)、X射线衍射仪(XRD)和X射线光电子能谱(XPS)等对制备的电极材料进行表征分析,探究FeCo2S4/NF电极材料微观结构和电化学性能之间的关联,并在三电极体系中测试电极材料的电化学性能,将其与活性炭组装成非对称超级电容器,测试其在二电极体系中的电化学性能。结果表明,以泡沫镍为基底的自支撑FeCo2S4纳米片彼此相互连接,形成具有大量空隙的三维纳米结构,促进了电极材料的高效电子传递和长期稳定,从而使FeCo2S4/NF自支撑电极材料具有优良的储能性能。
Abstract:
The self-supported FeCo2S4 electrode(FeCo2S4/NF)was synthesized by a two-step hydrothermal method using nickel foam(NF)as the substrate. The prepared electrodes were characterized and analyzed by SEM, XRD and XPS to explore the relationship between the microstructure and electrochemical properties of FeCo2S4/NF. The electrochemical performance of the electrode materials was tested in a three-electrode system. Furthermore, the asymmetric supercapacitor was assembled using activated carbon as cathode to test the electrochemical performance in a two-electrode system. The results showed that the self-supported FeCo2S4 nanosheets were interconnected with NF to form a three-dimensional nanostructure with numerous pores. Such unique structure significantly promoted the efficient electron transfer and long-term stability of the electrode material, thus making the self-supported FeCo2S4/NF electrode with excellent energy storage performance.
