Description
Molybdenum trioxide (MoO3), a potential supercapacitor electrode material is synthesized through hydrothermal method at low temperature. The significant charge-storage process of the MoO3 electrode is extensively analyzed in 0.5M sodium sulfate (Na2SO4) in a wide potential window. The basic functional properties of MoO3 are characterized through different characterization techniques. The electrochemical performance is examined through chargingdischarging method, cyclic voltammetry, and impedance spectroscopic studies of the active electrode with a mass loading of 1 mg cm?2 each. The three-electrode and device systems of the MoO3 electrode are also investigated. The specific capacitance obtained for the device is 295 F g?1 at 1 A g?1 in a potential window of 0 to 1V in 0.5M Na2SO4 electrolyte solution. The densities of energy and power are 40.27 W h kg?1 and 492 W kg?1. The device is further tested for cyclic stability over 1000 cycles and attained a stability of 75% and a Coulombic retention of 100%. This work demonstrates that the MoO3 electrode can be facilitated for the aqueous electrochemical energy storage devices.
