Description
Vanadium pentoxide (V?O?) flakes were synthesized via a hydrothermal method by varying the amount of lemon juice (5mL for sample-1 and 10mL for sample-2) as a natural chelating agent. Structural and morphological analyses were performed using X-ray diffraction (XRD) and scanning electron microscopy (SEM), confirming crystalline V?O? with flake-like morphologies influenced by chelating agent concentration. Electrochemical performance was evaluated using cyclic voltammetry (CV), galvanostatic chargedischarge (GCD), and electrochemical impedance spectroscopy (EIS) in a 3M KOH electrolyte. Sample-2 exhibited a Significantly higher Specific capacitance of 1536 F?g?1 (CV at 1mVs?1) and 212.37 F?g?1 (GCD at 1 A?g?1) compared to sample-1, demonstrating that increasing lemon juice concentration enhances the capacitive behavior of V?O? flakes by improving ion diffusion and electroactive surface area.
