The synthesized NiCo 2 S 4 @MnS/CC electrode shows high capacitance of 1908.3 F g −1 at a current density of 0.5 A g −1 which is higher than those of NiCo 2 S 4 and MnS at the same current density. A flexible all-solid-state asymmetric supercapacitor (ASC) is constructed by using NiCo 2 S 4 @MnS/CC as positive electrode, active carbon/CC as negative electrode and KOH/poly (vinyl alcohol) (PVA) as electrolyte. The optimized ASC shows a maximum energy density of 23.3 Wh kg −1 at 1 A g −1 , a maximum power density of about 7.5 kw kg −1 at 10 A g −1 and remarkable cycling stability. After 90 0 0 cycles, the ASC still exhibited 67.8% retention rate and largely unchanged charge/discharge curves. The excellent electrochemical properties are resulted from the novel core-shell structure of the NiCo 2 S 4 @MnS/CC electrode, which possesses both high surface area for Faraday redox reaction and superior kinetics of charge transport. The NiCo 2 S 4 @MnS/CC electrode shows a promising potential for energy storage applications in the future.

“…However, compared with the transition metal sulfides, TMOs have poor ionic transfer and conductivity, which limits their wide application in high‐speed devices to a certain extent . The electronegativity of sulfur is relatively lower than oxygen, which will make electrons transport easier . Besides, metal sulfide‐based composite electrode materials can provide significant electrochemical performance compared to pure metal sulfides .…”

Constructing hierarchical core‐shell configuration from well‐known metal sulfides is one way to further tune and utilize unique species. Herein, a novel core‐shell structure is developed based on CoS deposited on NiS nanosheets, which involves hydrothermal and electrodeposition method. The micromorphology of the composite electrode can be optimized by adjusting the cycles of electrodeposition. Taking advantages of the highly conductive, open framework of the core‐shell nanolayer, the 5‐NiS@CoS electrode shows a specific capacitance of 1210 F g−1 at a current density of 1 A g−1 (retaining 82% from 1 to 10 A g−1, while NiS substrate is only 39%). The specific capacitance retention rate is 80.94% at 10 A g−1 after 2000 cycles (NiS substrate is 59.6%). Moreover, NiS@CoS//AC asymmetric supercapacitor device delivers an energy density of 24.1 Wh kg−1 at a power density of 752.15 W kg−1 and remarkable stability (over 80% retention after 5000 cycles). This work may prompt the exploration of the synthesis of inexpensive compounds incorporating highly reactive components for supercapacitors.
