The introduction of pillared agents or dopants to the graphene used as electroactive material in supercapacitor electrodes can be an efficient way facilitate ion transfer, mitigate re-stacking, and improve electrochemical performance. We evaluated effect different precursors containing nitrogen (N) sulfur (S) atoms dope flake (GF) lattices. performance doped GF was assessed 1 M KOH Na2SO4 electrolytes. N- S-doped flakes were synthesized via mechanochemical synthesis, also known ball milling....
Decoupling energy supply from fossil fuels through electrification and sustainable management requires efficient environmentally low-impact storage technologies. Potential candidates are charge electrodes that combine nickel cobalt hydroxides with reduced graphene oxide (rGO) designed to achieve high-energy, high-power density long cycling lifetimes. An early eco-efficiency analysis of these seeks examine the impacts materials processes used in synthesis, specifically while focusing on use...
Revalorizing organic biowaste is critical to achieve a full circular economy, where waste transformed into resources. One of the main strategies produce activated carbons and use them as functional materials for electrochemical energy storage. In this study, winemaking wastes, bagasse (BAG), cluster stalks (CS) were recovered used in preparation by hydrothermal process. Then, they chemically using KOH investigated capacitor applications. The activation treatment resulted microporous...
This work reports, for the first time, use of ion-selective localized electrochemical techniques to elucidate charge-discharge mechanism nickel-cobalt hydroxide electrodes energy storage. The electrodeposited was studied in Na 2 SO 4 0.05 M by situ measurements pH, pNa and dissolved O during cyclic voltammetry. Local pH distributions were recorded using micro-potentiometric sensors with liquid membrane, while monitored a fiber-optic microsensor. These original results highlight how...
Nickel–cobalt oxyhydroxide has been delaminated by tetrabutylammonium (TBA+) intercalation in aqueous media. The electrochemical performance of the different materials obtained during delamination evaluated, with special emphasis on effect intercalated species and their influence behavior material, toward energy storage applications. Delamination TBAOH, reported for first time nickel–cobalt media, is an excellent route to increase number electrochemically active sites enhance capacity...
Hybrid capacitors have been developed to bridge the gap between batteries and ultracapacitors. These devices combine a capacitive electrode battery-like material achieve high energy-density power-density with good cycling stability. In quest of improved electrochemical responses, several hybrid proposed. However, they are usually limited bench-scale prototypes that would likely face severe challenges during scaling up process. The present case study reports production prototype consisting...
