Supercapacitors have increased considerable interest due to their unique characteristics such as extended life cycle, high-power density, and environmental friendliness. They serve as a bridge for the energy-power difference between a traditional capacitor and batteries/fuel cells. Selection of the ideal electrode material for a particular application is a critical parameter that affects the efficiency of supercapacitor devices. Transition-metal sulfides exhibit multiple oxidation states and display outstanding supercapacitance performance. Metal sulfides are comparatively superior than metal oxides because of their better conductivity, higher electrochemical activity, and eminent thermal and mechanical stability. A comprehensive summary of the zinc sulfide (ZnS)-based nanomaterials as supercapacitor electrodes is on view. With a band gap of 3.5−3.8 eV, ZnS is one of the first discovered II−VI semiconductors. ZnS has been revealed as a sustainable and promising supercapacitance electrode material owing to its facile synthesis and magnificent electrochemical performance. This review has covered the recent research and development of ZnS nanostructures for supercapacitor electrodes. Additionally, synthesis of ZnS nanostructures and influencing parameters, selection of composite materials, and their design have been summarized for highly efficient supercapacitor devices. As far as our knowledge, this review is the first holistic description of ZnS-based supercapacitor electrodes and devices from basics to recent advancements.

Supercapattery is an ideal energy storage device combining the features of supercapacitors and batteries, offers a high‐energy density as well as high‐power density with extended operational lifespan. In this work, zinc sulfide (ZnS) and zinc sulfide/nickel oxide (ZnS/NiO) nanocomposite was synthesized via chemical coprecipitation method and characterized using state‐of‐the‐art analytical tools. The ZnS/NiO electrode exhibited remarkable electrochemical performance as an electrode material than pure ZnS. The ZnS/NiO nanocomposite exhibited high crystallinity, and spherical nanoparticles with an average grain size of 20–40 nm having a homogeneous dispersion. The ZnS/NiO electrode exhibited an ultrahigh specific capacity of 1803.87 Cg−1 at a relatively low scan rate of 10 mVs−1 in a 1 M KOH solution from cyclic voltammetry and 393 Cg−1 at 16 Ag−1 from charge discharge measurements, and it showed exceptional cycling stability (98 % capacity retention after 1000 cycles). Furthermore, the ZnS/NiO symmetric supercapattery device exhibited 44.43 Fg−1 specific capacitance, 5.52 Wh kg−1 energy density, and 1600 Wkg−1 power density at current density of 0.8 Ag−1 in 1 M KOH solution from galvanostatic charge discharge. After 3000 cycles, the ZnS/NiO nanomaterial demonstrated promising cyclic stability of 95 %. The ZnS/NiO supercapattery nanocomposite might be considered as a potential hybrid electrode material for the future development of electrochemical energy storage devices.
