Cabbage-Like NiCo2S4/MoS2 Assemblies as Electrode Materials for Asymmetric Hybrid Capacitors

In this work, cabbage-like NiCo 2 S 4 /MoS 2 assemblies are prepared via a simple hydrothermal process. The as-prepared product as electrode material possesses a specific capacitance of 612 C g −1 at 1 A g −1 and 94% capacitance retention after 10000 cycles at 10 A g −1 . Furthermore, the as-assembled asymmetric supercapacitor exhibits an energy density of 73.3 Wh kg −1 at a power density of 453.4 W kg −1 . It demonstrates that the cabbage-like structures present promising applications in future energy storage devices.
