Mesoporous Nanohybrids of 2D Ni‐Cr‐Layered Double Hydroxide Nanosheets Pillared with Polyoxovanadate Anions for High‐Performance Hybrid Supercapacitor

“…[ 19,20 ] The transition metal LDHs and their hybrids are emerged as battery‐type HSC electrode materials due to their multiple redox properties and special layered structure that can accommodate a large amount of charge storing ions. [ 1,21–25 ] The performance of recently reported LDHs and their hybrids as HSC cathodes are summarized, as shown in Figure . [ 21–39 ]…”

Hybrid structured CoNi2S4/Ni3S2 nanowires with multifunctional performance for hybrid capacitor electrodes and overall water splitting

“…In recent years, various transition metal-based catalysts such as phosphides, oxides, nitrides, carbides, and suldes have been widely investigated as excellent electrochemical catalysts but the improvement of bi-functional electrocatalysts with excellent HER and OER activity is still difficult and slow to implement. [1][2][3][4] To date, as demonstrated by experiments, electrocatalysts with vertically well-aligned arrays on 1D nanostructures consistently lead to improved HER and OER activity and promise efficient overall water splitting. 5,6 Nanostructures possess distinctive advantages, including easier electrolyte diffusion and ionic transportation, better electrical connection with substrates, and offer larger surface area to provide contact between the electrode and electrolyte.…”

High-performance flexible hybrid supercapacitor based on NiAl layered double hydroxide as a positive electrode and nitrogen-doped reduced graphene oxide as a negative electrode

“…Even though high capacity values have been achieved, LDHs-based electrodes possess a relatively small operating potential window range, usually from 0 to 0.6 V [25][26][27]. Therefore, the fabrication of hybrid supercapacitors with battery-type materials as positive electrodes and carbon-based materials with large operating potential windows as negative electrodes represents an interesting approach for improving the overall energy density [28][29][30][31][32].…”
