“…Supercapacitors are such energy storage devices that they have high power density than batteries and high energy density than dielectric capacitors. Prominent features of supercapacitors include high durability, fast charging, larger cycling time, low maintenance cost, and long life 6,7 . The performance of a supercapacitor depends on three factors: electrode material, electrolyte, and arrangement of the assembled device.…”

The growth in energy devices and the role of supercapacitors are increasingly important in today’s world. Designing an electrode material for supercapacitors using metals that have high performance, superior structure, are eco-friendly, inexpensive and highly abundant is essentially required for commercialization. In this point of view, quaternary chalcogenide Cu2NiSnS4 with fascinating marigold flower like microstructured electrodes are synthesized using different concentrations of citric acid (0, 0.05 M, 0.1 M and 0.2 M) by employing solvothermal method. The electrode materials physicochemical characteristics are deliberated in detail using the basic characterization techniques. The electrochemical studies revealed better electrochemical performances, in particular, Cu2NiSnS4@0.1 M-CA electrode revealed high 1029 F/g specific capacitance at 0.5 A/g current density. Further, it retained 78.65% capacity over 5000 cycles. To prove the practical applicability, a full-cell asymmetric solid-state device is fabricated, and it delivered 41.25 Wh/Kg and 750 Wh/Kg energy and power density at 0.5 A/g. The optimum citric acid added Cu2NiSnS4 electrode is shown to be a promising candidate for supercapacitor applications.

Ternary spinel MnCo 2 S 4 spherical nanoparticles are prepared through a simple one step hydrothermal approach with precursors followed by an ion exchange reaction. The obtained spherical nanoparticles offers a high specific surface area with mesoporous structure, this aids in providing outstanding electrochemical performance with a specific capacitance of 707.77 F/g at 2 A/g and a good cyclic stability (initial capacitance of 95.15% after 10000 cycles). It offers a high energy density of 78.17 W h Kg −1 to satisfy the commercial needs. By the utilization of structural and electrochemical benefits, MnCo 2 S 4 electrode establishes its significant potential in the field of energy storage system.

“…An electrical double layer capacitor is a collection of charge separation and an interface between the electrode and electrolytes. 11,12 Transition metal suldes (TMSs), such as CuS/Cu 2 S, 13,14 NiS, 15 MoSe 2 16 SnS 2 , 17 ZnS, 18 CoS, 19 FeS, 20 MoS 2 , and WS 2 , 21,22 have been exhaustively studied as an electrochemically active material for supercapacitor performance. MoS 2 is a highly studied TMSs compared to other metal suldes, as well as the most important material scientically and for industrially applications because of the different oxidation state with polymorphism, distinctive surface morphology structure, atomic structure, tremendous physical, chemical stability, electroactive properties, direct band gap, and small thickness, unique layered structure, wide specic surface area, good specic capacitance, and reported high electrochemical properties.…”
