“…Recently, Hou et al synthesized a core–shell heterostructure of NiS 2 @MoS 2 that delivers a specific capacitance of 842.4 F/g at 1 A/g with a capacitance retention of 83.1% over 10 000 GCD cycles . NiS@Co 3 S 4 synthesis via the hydrothermal method by Mahieddine et al shows a high specific capacitance of 1893 F/g with a cyclic stability of 98.63% over 10 000 charge–discharge cycles . In this view, the core–shell-based MoS 2 and FeS 2 (“core” FeS 2 and “shell” MoS 2 ) heterostructure could be a good alternative for the quasi-solid-state supercapacitor.…”

Metal chalcogenides with heterostructures exhibit fascinating structures and properties, enabling them to be used in various applications. In this work, we developed a core−shell heterostructure of MoS 2 @FeS 2 via a two-step hydrothermal and solvothermal method and explored its electrochemical performance in a quasi-solid-state symmetric and asymmetric supercapacitor. This unique heterostructure comprises MoS 2 nanoflakes decorated over octahedron-like FeS 2 , which enhances the electron/ion mobility and provides more number redox sites to boost the electrochemical performance. The symmetric configuration exhibits a maximum specific capacitance of ∼386 F/g at a current density of 1 A/g, with an excellent capacitance retention of ∼90.3% over continuous 10 000 charge/discharge cycles at 10 A/g. Further, the heterostructure shows a high energy density of ∼53 Wh/kg at a power density of ∼699 W/kg. At the same time, the asymmetric configuration delivers a maximum capacitance of ∼186 F/g with energy and power density values of ∼29 Wh/kg and ∼900 W/kg, respectively. Two asymmetric cells connected in series can illuminate red and blue LEDs, conforming to their practical application. It is believed that the MoS 2 @FeS 2 core−shell heterostructure can be a promising electrode material for supercapacitor application.
