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.

An electrochemical capacitor configuration extends its operational potential window by leveraging diverse charge storage mechanisms on the positive and negative electrodes. Beyond harnessing capacitive, pseudocapacitive, or Faradaic energy storage mechanisms and enhancing electrochemical performance at high rates, achieving a balance of stored charge across electrodes poses a significant challenge over a wide range of charge–discharge currents or sweep rates. Consequently, fabricating hybrid and asymmetric supercapacitors demands precise electrochemical evaluations of electrode materials and the development of a reliable methodology. This work provides an overview of fundamental aspects related to charge‐storage mechanisms and electrochemical methods, aiming to discern the contribution of each process. Subsequently, the electrochemical properties, including the working potential windows, rate capability profiles, and stabilities, of various families of electrode materials are explored. It is then demonstrated, how charge balancing between electrodes falters across a broad range of charge–discharge currents or sweep rates. Finally, a methodology for achieving charge balance in hybrid and asymmetric supercapacitors is proposed, outlining multiple conditions dependent on loaded mass and charge–discharge current. Two step‐by‐step tutorials and model examples for applying this methodology are also provided. The proposed methodology is anticipated to stimulate continued dialogue among researchers, fostering advancements in achieving stable and high‐performance supercapacitor devices.
