Energy storage is one of the challenges currently confronting the energy sector. However, the invention of supercapacitors has transformed the sector. This modern technology’s high energy capacity, reliable supply with minimal lag time, and extended lifetime of supercapacitors have piqued the interest of scientists, and several investigations have been conducted to improve their development. However, there is room for improvement. Consequently, this review presents an up-to-date investigation of different supercapacitor technologies’ components, operating techniques, potential applications, technical difficulties, benefits, and drawbacks. In addition, it thoroughly highlights the active materials used to produce supercapacitors. The significance of incorporating every component (electrode and electrolyte), their synthesis approach, and their electrochemical characteristics are outlined. The research further examines supercapacitors’ potential in the next era of energy technology. Finally, concerns and new research prospects in hybrid supercapacitor-based energy applications that are envisaged to result in the development of ground-breaking devices, are highlighted.

Summary The behavior of Prussian Blue Analogs (PBAs) is determined by the external transition metal coordinated to the N‐end of the hexacyanoferrate block. Combining transition metal ions allows obtaining a material with improved performance for energy‐related applications. A mixed PBA was formed with cobalt hexacyanoferrate (CoHCF) and ZnHCF. The former has two redox processes and easy modulation of its morphology, while the latter exhibits fast kinetics during the charge transfer. The morphology of the solids was controlled by composition, shaping hollow structures at a high concentration of Co2+ in the PBA. Spectroscopic characterization displayed the change in the charge density at the N‐end of the cyanide bridges caused by the polarizing power of Zn2+. XRD showed the formation of more than one crystalline phase. The presence of Co2+ provided larger specific capacity and stability during cycling, while Zn2+ afforded a higher potential and improved rate capability to the solid. The material with the best electrochemical behavior was employed to assemble a hybrid supercapacitor, reaching specific energy of 30 Wh kg−1 at a power of 450 W kg−1 and 7 Wh kg−1 at 5.5 kW kg−1. Additionally, the device retained 85% of its initial capacitance after 5000 galvanostatic charge–discharge cycles.

Bi2O3 nanosheets (NSB) photocatalyst was fabricated via a very simple method of liquid precipitation. The as obtained products were characterized by SEM, N2 adsorption-desorption, XRD and UV-vis diffuse reflectance spectra. The results showed that NSB catalyst can beconsidered as set of nanosheets with an average thickness of 110 nm. NSB photocatalyst exhibited high surface area of 33.21 m2/g and high purity. In addition, NSB catalyst displayed excellent photocatalytic performance for the dye of rhodamine B (Rh B) under visible light due to the structure of sheet and high surface area.
