Abstract: Researchers are now paying close attention to nanostructured metal vanadates because of their exceptional capabilities in energy conversion, electronic devices, catalysis and storage. The Mo4V6O25 nanostructures was prepared via easy wet chemical method. The prepared Mo4V6O25 was examined using a variety of analytical and spectral methods. Because of their abundance, relative affordability, and multiple oxidation states, molybdenum and vanadium may generate a wide range of redox reactions that are advantageous for electrochemical function. The developed Mo4V6O25 nanostructures can also be utilized as efficient material for supercapacitors (SCs) because of their superior features and easy passage of ions. They demonstrated notable efficiency with significant specific capacity (Cs) of 203 C/g at 1 A/g. Additionally, it shows good cyclic stability and coulombic efficiency (89.5% and 83.5 even after 10,000 cycles at 1 A/g). The nanoflakes-like structure of Mo4V6O25 is the best option for use in SCs attributable to its significant high-rate capability as well as cycle stability. After assembling with activated carbon (AC) to form a Mo4V6O25//AC device, the energy density (ED) of this Mo4V6O25//AC device is 56.9 Wh/kg at a power density (PD) of 1125 W/kg, and remains at a 15 Wh/kg at a power density of 4500 W/kg. The findings suggest that Mo4V6O25 nanostructures are excellent options for high-efficiency energy storage systems. [ABSTRACT FROM AUTHOR]
