Abstract 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 at 1 mA/cm2. Furthermore, the hybrid capacitor unveils an energy density of 35.93mWh/cm3 at a power density of 1064.76mW/cm3. The observed results clearly revealed that the synthesizedMoS2/Ni3S2 structure might be used as potential electrode material for future energy storage devices.
