High performance hybrid supercapacitor based on hierarchical MoS2/Ni3S2 metal chalcogenide

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 MoS/NiSstructures grown on nickel foam by a facile one-pot hydrothermal process. The as-fabricated asymmetric hybrid capacitor based on hierarchical MoS/NiSelectrode exhibit a specific capacitance of ～1.033 C/cm~2 at1 mA/cm~2. Furthermore, the hybrid capacitor unveils an energy density of 35.93 m W h/cm~3 at a power density of 1064.76 mW/cm~3. The observed results clearly revealed that the synthesized MoS/NiSstructure might be used as potential electrode material for future energy storage devices.
