Efficient pH-universal aqueous supercapacitors enabled by an azure C-decorated N-doped graphene aerogel

Developments in conducting polymer-, metal oxide-, and carbon nanotube-based composite electrode materials for supercapacitors: a review

“…95,96 Graphene is a unique carbon derivative that has the potential to be used in ESD applications due to its exceptional properties of appreciable conductivity, chemical stability, and broad surface for adsorption and catalytic reactions. [97][98][99][100] The use of graphene as a material for SC applications has recently been proposed because, unlike many other carbon materials like AC and CNTs, graphene's usage as an electrode material for SCs does not depend on the dispersion of pores in the solid state. 100,101 The SSA of newly synthesized graphene, which is about 2630 m 2 g −1 , is larger than that of any other carbon-based nanomaterials used in the fabrication of electrodes in EDLCs.…”

Binary Ni–Cu nanocomposite-modified MXene-adorned 3D-nickel foam for effective overall water splitting and supercapacitor applications

“…29–31 Alternatively, due to their long life, excellent power density, and good charging/discharging rate, supercapacitors have attracted significant attention from researchers for use in portable electrical gadgets. 32–34 However, their poor energy density limits their application in industry. Supercapacitors can be classified based on their charge storage mechanism into faradaic pseudocapacitors and non-faradaic electric double-layer capacitors, where pseudocapacitors demonstrate a higher energy density.…”

Self-supported 3D coral-like copper/poly diphenylamine on nickel foam: multifunctional exploration of overall electrochemical water splitting, alcohol oxidation reaction and supercapacitor applications

“…1–3 Energy storage and conversion devices have been garnering a lot of fascination from researchers worldwide in recent years, as a consequence of the significant advancements made in the realm of nanoscience. 2 Electrode materials, which are responsible for the electron transfer that is generated at the electrode/electrolyte interfaces, are at the core of energy conversion and storage systems, including supercapacitors, 4–9 batteries, 10 solar cells 11 and fuel cells. 12–14 For optimal functioning electrochemical devices, electronic conduction via the electrode in conjunction with the viable redox reactions occurring at the electrode/electrolyte interface is exceptionally important.…”
