Hydrothermal Method-Derived MnMoO4Crystals: Effect of Cationic Surfactant on Microstructures and Electrochemical Properties

The development of energy devices is becoming necessary to deal with the power crisis. Binary transition manganese molybdate (MnMoO4) is considered to be a well-known material for storage applications. Electrochemical performance of anode electrode materials was tested with respect to the effect of cationic surfactant cetyltrimethylammonium bromide (C19H12BrN). The fundamental characterization studies such as X-ray diffraction, photoluminescence, Raman, and Fourier transform infrared confirmed the presence of MnMoO4. The scanning electron microscopic (SEM) images revealed well-grained micro/nanostructures. The electrochemical behavior was determined by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy studies. In this study, 0.2 M CTAB/MnMoO(4)showed high 447.61 F/g specific capacitance from the CV analysis. The GCD studies showed that after 3000 cycles, the cycling stability was retained with 79.60% of capacitive retention.
