- Abstract
The demand for supercapacitors and numerous high-performance energy storage applications have been the focus of intense research because the interest in electric vehicles and wearable technology is expanding rapidly. In this report, we have developed a microspherical MoO3 morphology on conducting FTO substrate from an electrodeposition method and it is used as an electrode for supercapacitor application. The structural, morphological, and electrochemical performance of the MoO3 electrodes were completely tested. Characteristic peaks from XRD patterns identified a well-crystalline orthorhombic structure of MoO3 thin film. RAMAN spectra show Mo–O bond stretching present in synthesized samples. Electrochemical studies of the films were observed by cyclic voltammetry (CV), galvanostatic charge–discharge (GCD), and electrochemical impedance spectroscopy (EIS). The electrode exhibits a specific capacitance of 281.27 mF cm−2 in a 1 M H2SO4 electrolyte with a specific energy of 12.99 mWh cm−2. The present research demonstrated that electrochemical deposition is a promising method for fabricating MoO3 electrodes for aqueous electrochemical energy storage.
