In this study, a facile one-pot hydrothermal route has been employed for the preparation of Cu3SbS4 nanoplates and its use as an electrode material for supercapacitors has been demonstrated. The physicochemical characterizations such as X-ray diffraction, X-ray photoelectron spectroscopy, high-resolution transmission electron microscope, and laser Raman spectroscopic studies revealed the formation of Cu3SbS4 with plate-like structures. The electrochemical properties of the Cu3SbS4 electrodes was studied using cyclic voltammetry (CV), galvanostatic charge-discharge (CD) and electrochemical impedance spectroscopy (EIS) analyses. The CV analysis indicated the presence of a pair of redox peaks suggesting the pseudocapacitive nature of the Cu3SbS4 electrode with a high specific capacitance of 60 F g1 (obtained at a scan rate of 5 mV s1). The Cu3SbS4 electrode possess a specific capacitance of about 41.78 F g1 obtained from the CD profiles recorded using an applied current of 0.25 mA. The Cu3SbS4 electrode possess a high energy of about 11.375Wh kg1 and power density of 175Wkg1 with excellent cyclic stability over 2500 cycles. The collective findings of this work suggested that the use of Cu3SbS4 nanoplates as an advanced electrode for supercapacitor applications.
