FeCo2S4/NF自支撑电极的制备及其电化学性能
Preparation of self-supported FeCo2S4/NF electrode and its electrochemical properties
摘要
Abstract
The self-supported FeCo2S4 electrode(FeCo2S4/NF)was synthesized by a two-step hydro-thermal 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 elec-trochemical properties of FeCo2S4/NF.The electrochemical performance of the electrode materials was tested in a three-electrode system.Furthermore,the asymmetric supercapacitor was assembled u-sing 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.关键词
