Creating oxygen-vacancies in MoO3- nanobelts toward high volumetric energy-density asymmetric supercapacitors with long lifespan

A 2D metal–organic framework/reduced graphene oxide heterostructure for supercapacitor application

“…Materials like carbon, conducting polymers, transition metals and MOFs have been under study for supercapacitor applications. [4][5][6][7][8][9][10][11][12][13][14] Among these MOF are materials made of transition metals and organic linkers and emerged as a new class of supercapacitor electrode materials with tuneable porosity, large specic surface area and excellent physical and chemical properties. 15 The combined high surface area and redox-active metal centres makes MOFs promising material for energy storage application.…”

Atomic Modulation Triggering Improved Performance of MoO3 Nanobelts for Fiber‐Shaped Supercapacitors

“…Molybdenum trioxides (MoO 3 ) are of great potential as electrode materials due to their unique characteristics such as low cost, various valence states, and eco‐friendly . Additionally, the MoO 3 possesses a high work function of 6.9 eV, which enables a broader operation voltage window for ASCs . However, the MoO 3 displays a low electrical conductivity (≈10 −7 S cm −1 ) as a result of the wide bandgap of ≈3 eV, which severely impedes its applications in FSCs devices .…”

Coupling Alkaline Conversion Zn Anode with Acidic Proton-insertion MoO3 Cathode for High-voltage Aqueous Rechargeable Hybrid Battery

“…21,22 Accordingly, efforts have been made to improve the conductivity of α-MoO 3 , typically by coating of conductive polymers on the surface of MoO 3 , 23,24,25 such as polyaniline (PANI), polypyrrole (Ppy), owing to their merits of good stability, low cost, and good conductivity, which is bene cial to facilitate electrons transfer and to expedite ions exchange, in this manner can the associated performance be improved to a certain extent, there is great space for further improvement yet. 26,27 The bottleneck for such electrochemical device with non-mental ions storage is the thermal stability windows of 1.23 V, which greatly limits the energy density that is directly related to the working voltage according to the equation (E = C sp * V). 28,29 Hybrid electrochemical devices by coupling acidic cathode with alkaline anode were reportedly to be capable of broadening the voltage window of aqueous battery, 30,31,32,33,34,35 which inspire us to accomplish the idea to develop dual-nonmetal ions H + /OHbattery.…”
