In this study, bimetallic cobalt-vanadium-based layered double hydroxide (CoV-LDH) systems were developed by varying the Co/V molar ratios (1:1 and 2:1) hydrothermal temperatures (120 180 °C). Structural analysis X-ray diffraction (XRD), Raman, Fourier-transform infrared (FTIR) spectroscopy indicated successful formation of CoV-LDH with a unique structure lattice distortions, reflecting influence both metal concentrations temperature on crystal chemical structures systems. Similarly, field-emission scanning electron microscopy (FESEM) high resolution transmission (HRTEM) images revealed flaky 2D nanosheet-like for 1:1 ratio prepared at 120 °C (CVL1-120), whereas one-dimensional (1D) three-dimensional (3D) morphologies observed other different (2:1) and/or (180 Electrochemical performed in three-electrode setup demonstrated specific capacitance 314.4 F g-1 1 A current density CVL1-120, which is ∼4.5 5.2 times higher than those monometallic Co V-LDH, respectively. addition, CVL1-120 exhibited an excellent retention ∼97% over 5000 charge-discharge cycles 100% Coulombic efficiency 10 g-1. Furthermore, asymmetric device delivered energy 36.5 Wh kg-1 power 1208.2 W kg-1. This enhanced performance was attributed to its two-dimensional (2D) structures, rich intercalated ions serving as electroactive sites, facilitating charge storage improved stability, making it suitable electrode material sustainable supercapacitors.
