“…The resulting G-Nb 2 O 5 nanosheets not only showed a mesoporous and thin characteristic, but also exhibited a vertical (001) facet with a large lattice spacing of 3.9 Å, providing a large amount of open and short channels for the rapid Na + diffusion. 139 However, owing to the R Na + = 1.02 Å being larger than R Li + = 0.76 Å, 140,141 large volume changes and irreversible phase changes occurred during the Na + intercalation and deintercalation, especially at high current rates. 142 To date, many Wadsley-Roth (W-R) structured oxides have been reported as one of the most promising anode representatives due to their compelling rate performance featured with their wide channels.…”

In this study, we describe the effective production of a hybrid heterostructure consisting of reduced graphene oxide (rGO) and nanoparticles of manganese doped nickel oxide. The Mn doped NiO/rGO material characteristics were effectively studied by various analytical methods. The Mn doped NiO@rGO exhibits exceptional electrochemical features as an electrocatalytic material supercapacitor, including extremely high specific capacitance (C s ) of 1780.32 F g −1 at 1.0 A g −1 , ideal rate capability of 1720 F g −1 , and exceptional life cycle of 4% (96%) capacitance rate decline over 6000 cycles. Importantly, the kinetic analysis shows that capacitance dominates the diffusion process throughout the charge storage mechanism. The hybrid nanocomposite exhibited stable behavior for 60 h compared with the benchmark (RuO 2 ). As a result, the Mn doped NiO@rGO electrode design might be considered a potential electrode with high C s for future energy conversion equipment.

“…There has been a lot of research conducted on improved energy conversion and saving due to the vital need for renewable and environmentally friendly energy reservoirs in the latest electronic sector. − Supercapacitors (SCs) have emerged as one of the most competitive and alluring options for future power devices in the realm of practical energy saving and transformation techniques. − They have excellent qualities such as long cycle life, high S P , and quick charging/discharging (C/D) rates. − An electrochemical double-layer material is necessary for both the electrochemical double-layer capacitor (EDLC) and the pseudocapacitor; the EDLC is principally dependent on the buildup of hydroxyl ions on the electrolyte/electrode surface. − The parameters of a SC’s electroactive material have a significant impact on its electrochemical performance. − Supercapacitors (SCs) have been studied using a board spectrum of electrode species, including metal oxides (MO x ), conducting polymers, carbon-based substances, and spinel materials. − With these materials, the electrical conductivity, cycle life, and volume expansion have all been disappointing. Both the effectiveness of SCs and the nanostructures of electrode materials have increased over time. , …”

Supercapacitors (SCs) possess specialized capabilities and exhibit rapid charging and discharging rates, making them highly suitable for integration into portable energy storage and conversion devices. These devices have witnessed a notable surge in demand and are increasingly contributing to the overall progress of the global energy industry. However, the bimetallic sulfide displays a high energy density, and high capacitance helps to resolve the limitation of monometallic sulfide. This study examines the advantageous characteristics of AgBiS2 as a viable energy storage medium in electrochemistry. These characteristics encompass a high level of electrical conductivity and a relatively low cost. AgBiS2 nanostructures were effectively synthesized in the laboratory by utilizing a straightforward hydrothermal method. The produced nanostructure of AgBiS2 is subjected to a range of evaluations encompassing electrochemical and physiochemical analyses. A specimen of AgBiS2 was positioned onto a substrate composed of nickel foam to facilitate measurement of its capacitance. The combined effect of Ag and rate and the supercapacitor’s electrochemical performance. The galvanometric charge–discharge (GCD) profile of an AgBiS2 nanostructure, obtained using a three-electrode configuration in 2.0 M KOH, demonstrates a specific capacitance (C s) of 650 F g–1 at 1 A g–1 current density. Additionally, the nanostructure exhibits a capacitive retention of 89% over 7000 cycles within the potential range 0–0.6 V (Ag/AgCl). When subjected to symmetric analysis, the AgBiS2 electrode exhibits a significant specific capacitance (C s) of 401 F g–1. This high capacitance is observed at 1 A g–1 in a two-electrode setup, employing an aqueous electrolyte of 2.0 M KOH. The symmetric AgBiS2 electrode-based supercapacitor exhibits a specific energy (S E) of 65 Wh kg–1 and a specific power (S P) of 0.28 W kg–1. The capacitive outcomes depend on the larger interfacial area, synergistic effect, and low resistance value. According to capacitive investigations, the AgBiS2 electrode exhibits potential utility in various domains, including but not limited to supercapacitor applications, photocatalysis, water splitting, and water remediation.
