“…1 In conventional capacitors, the separator used is called dielectric, which prevents the moving of charges between the electrodes. Supercapacitors comprise 4 major components, namely, current collector, electrode materials that consist of electroactive materials, electrolyte, and the separator.…”

Summary The research on electrode materials for supercapacitor application continues to evolve as the request of high‐energy storage system has increased globally due to the demand for energy consumption. Over the past decades, various types of carbon‐based materials have been employed as electrode materials for high‐performance supercapacitor application. Among them, graphene is 1 of the most widely used carbon‐based materials due to its excellent properties including high surface area and excellent conductivity. To exploit more of its interesting properties, graphene is tailored to produce graphene oxide and reduced graphene oxide to improve the dispersibility in water and easy to be incorporated with other materials to form binary composites or even ternary composites. Nowadays, ternary composites have attracted enormous interest as 2 materials (binary composites) cannot satisfy the requirement of the high‐performance supercapacitor. Thus, many approaches have been employed to fabricate ternary composites by combining 3 different types of electroactive materials for high‐performance supercapacitor application. This review focuses on the supercapacitive performance of graphene‐based ternary composites with different types of active materials, ie, conducting polymers, metal oxide, and other carbon‐based materials.

“…However, the fatal 2 drawbacks of single metal oxide were low electronic conductivity and short cyclic lifetime. It was reported that their composited or binary metal oxides had better capacitive behavior compared with the single metal oxides [7,8], due to their variable oxidation states and high electronic conductivity [9]. Hence, binary metal oxide electrodes might be the next-generation high-performance electrode materials for electrochemical energy storage devices.…”

In our study, we report a facile solvothermal method for the synthesis of Bi 2 S 3 nanoparticles with unique morphologies using water and mixed solvent systems, such as ethylene glycol/water (1:1, v/v) and butyldiglycol/water (1:1, v/v). Altering the solution mixtures used in the solvothermal synthesis allowed the shape of the Bi 2 S 3 nanoparticles to be controlled. The synthesis of Bi 2 S 3 in water at 150°C for 24 h led to the formation of sphere-like particles 100-300 nm in size. Very uniform spherical nanospheres with diameters from 50 to 90 nm formed when ethylene glycol/water mixture (1:1, v/v) was used as the solvent under the same solvothermal conditions. The butyldiglycol/water mixture promoted the formation of plate-shaped Bi 2 S 3 nanoparticles composed of nanorods. The electrochemical properties of the Bi 2 S 3 samples were determined in a three-electrode cell in 6 mol L -1 KOH using cyclic voltammetry, galvanostatic charging/discharging and impedance spectroscopy. Among the synthesized materials, the Bi 2 S 3 sample obtained in the butyldiglycol/water mixture exhibited a superior capacitive behavior with an outstanding capacitance of 550 F g -1 (at 0.5 A g -1 ), and great cycle stability, which was reflected by a capacitance retention of 87% after 500 charge/discharge cycles. These results demonstrate the high potential of Bi 2 S 3 as an active electrode material for supercapacitors.
