Abstract Amelioration of nickel‐cobalt layered double hydroxides (NiCo‐LDH) with a high specific theoretical capacitance is great desire for high‐power supercapacitors. Herein, molybdenum (Mo) doping strategy proposed to improve the charge‐storage performance NiCo‐LDH nanosheets growing on carbon cloth (CC) via rapid microwave process. The regulation electronic structure and oxygen vacancy LDH consolidated by density functional theory (DFT) calculation, which demonstrates that Mo narrows band gap, reduces formation energy hydroxyl vacancies, promotes ionic charge transfer as well electrolyte adsorption electrode surface. optimal Mo‐doped (MoNiCo‐LDH‐0.05/CC) has an amazing capacity 471.1 mA h g −1 at 1 A , excellent retention 84.8% 32 far superior NiCo‐LDH/CC (258.3 76.4%). constructed hybrid supercapacitor delivers 103.3 W kg power 750 retains cycle 85.2% after 5000 cycles. Two assembled devices in series can drive thirty LED lamps, revealing potential application prospect rationally synthesized MoNiCo‐LDH/CC energy‐storage material.

Abstract The unparalleled morphological tuning of layered double hydroxides (LDHs), specifically NiCo(OH) 2 , through fluorine doping, is systematically investigated. unique achieved by precisely modulating the dopant concentration using a straightforward solvothermal approach. Field Emission Scanning Electron Microscopy (FESEM) results show distinct succulent‐like morphologies in samples, influencing surface area and electrochemical performance. Electrochemical studies fabricated asymmetric supercapacitor consisting 2F‐NiCo(OH) |Activated Carbon(AC) electrodes exhibit very high charge storage capacity as 402 C g −1 . Further, X‐ray photoelectron spectroscopy analysis confirms incorporation chemisorption within LDH layers, thereby corroborating its presence electronic environment enhancing device shows an exceptionally energy density, 67 Wh kg with power density 10.6 kW while retaining 95% specific after 13 000 cycles at 10 mA cm −2 current density. practical applicability developed demonstrated successfully powering LED calculator, underscoring potential for real‐world solutions.
