摘要
Recently,because of excellent electrical conductivities and many active sites,transition metal sulfides have been utilized as efficient electrodes for supercapacitors.Herein,we synthesize hierarchical MoS2/Ni3S2 structures grown on nickel foam by a facile one-pot hydrothermal process.The as-fabricated asymmetric hybrid capacitor based on hierarchical MoS2/Ni3S2 electrode exhibit a specific capacitance of^1.033 C/cm2 at1 mA/cm2.Furthermore,the hybrid capacitor unveils an energy density of 35.93 m W h/cm3 at a power density of 1064.76 mW/cm3.The observed results clearly revealed that the synthesized MoS2/Ni3S2 structure might be used as potential electrode material for future energy storage devices.
Recently, because of excellent electrical conductivities and many active sites, transition metal sulfides have been utilized as efficient electrodes for supercapacitors. Herein, we synthesize hierarchical MoS2/Ni3S2 structures grown on nickel foam by a facile one-pot hydrothermal process. The as-fabricated asymmetric hybrid capacitor based on hierarchical MoS2/Ni3S2 electrode exhibit a specific capacitance of ～1.033 C/cm2 at1 mA/cm2. Furthermore, the hybrid capacitor unveils an energy density of 35.93 m W h/cm3 at a power density of 1064.76 mW/cm3. The observed results clearly revealed that the synthesized MoS2/Ni3S2 structure might be used as potential electrode material for future energy storage devices.
