Oxygen defect-mediated NiCo2O4 nanosheets as the electrode for pseudocapacitors with improved rate capability

“…11,12 These advantages are beneficial for surfacedominated pseudocapacitance charge transfer and storage at high current density. 13 Up to now, various 2D pseudocapacitive electrode materials such as metal oxides/hydroxides, 14 metal dichalcogenides, 15 metal carbides, 16 metal nitrides, 17 metal phosphides, 18 carbon-based materials, 19 conducting polymers, 20 etc., have been investigated for supercapacitors. Among them, spinel NiCo 2 O 4 has drawn particular attention due to its low cost, high availability, complex chemical composition and multiple cation valence.…”

Review of NiS-Based Electrode Nanomaterials for Supercapacitors

“…Against this background, the supercapacitor—a new type of green energy storage device—has been developed. High power, a long life, and high reliability are the advantages of double-layer supercapacitors [ 17 , 18 , 19 , 20 ], which have been widely used in multifunctional electronic products, power systems, military components, and other high-peak-power fields [ 21 , 22 , 23 , 24 , 25 ].…”

Two-Dimensional Nanoarchitectonics for Two-Dimensional Materials: Interfacial Engineering of Transition-Metal Dichalcogenides

“…Since the successful preparation of graphene, two-dimensional (2D) materials having exclusive physical and chemical assets have attracted much interest for potential applications in catalysis, energy, electronics, transistors, and optoelectronics. − From the library of 2D materials, TMDs have recently attracted attention from scientific research and industry owing to their exclusive crystal structures and different material properties. − TMDs are generally denoted as MX 2 , where M represents a transition metal squeezed in two chalcogens X (X: S, Se, and Te atoms) in a single cell . Metals from groups 4 to 10 have different numbers of electrons in their d orbitals and filling, resulting in diverse electronic assets such as insulators, semiconductors, semimetallics, metallics, and superconductors. − This comprehensive series of electronic properties not only elevates the progress of TMDs in electronics and optoelectronics but also enables promising bids in catalysis and energy. − Furthermore, different TMD atomic arrangements are vital in defining material properties .…”
