Nanoarchitechtonic Marvels: Pioneering One-Pot Synthesis of Bi2WO6 Nanostructures for Breakthrough in Symmetric Supercapacitor Innovation

“…The modern era’s increasing energy consumption is propelling advancements in finding alternate energy sources and in developing advanced storage devices. − The demands of a growing population, the strains of global economic expansion, and the depletion of fossil fuels underscore the urgent need for innovative techniques in energy storage systems. , Supercapacitors are becoming increasingly popular in the energy storage industry because of their improved characteristics, including better cyclability, resilience, and high-power output. These traits distinguish them from regular capacitors and batteries. , Although conventional batteries and capacitors are still viable solutions, supercapacitors are distinguished by their enhanced power and energy densities, effectively addressing difficulties with both. , Electrical double-layer capacitors (EDLCs) and pseudocapacitors (PCs) are the two primary subcategories of supercapacitors, classified on the mechanism of energy storage. ,,− Supercapacitors’ efficacy is significantly influenced by the characteristics of the materials utilized for the active electrode. − EDLC electrodes are traditionally carbonaceous materials such as graphene-like carbon made from biomass, carbon nanotubes (CNTs), and carbon nanofibers (CNFs). , Conversely, PCs employ pseudocapacitive materials such as conducting polymers, metal hydroxides, and oxides, which support redox reactions through charging and discharging process. − Hybrid capacitors combine the physical adsorption of ions at the interface of the electrode and electrolyte with chemical redox processes by integrating EDLC and PC materials as two individual electrodes or merging them to form a single hybrid electrode. − …”
