文摘 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_2/Ni_3S_2 structures grown on nickel foam by a facile one-pot hydrothermal process. The as-fabricated asymmetric hybrid capacitor based on hierarchical MoS_2/Ni_3S_2 electrode exhibit a specific capacitance of ~1.033 C/cm~2 at 1mA/cm~2. Furthermore, the hybrid capacitor unveils an energy density of 35.93mWh/cm~3 at a power density of 1064.76mW/cm~3. The observed results clearly revealed that the synthesizedMoS_2/Ni_3S_2 structuremight be used as potential electrode material for future energy storage devices.
