“…Notably, at low scan rates, the collected curves did not feature a rectangular shape, evidencing the presence of both electric double-layer capacitor and pseudocapacitance mechanism. 26 At higher scan rates, considerable positive and negative shifts were observed for the anodic and the cathodic peak, respectively. Moreover, the peak currents in the CV voltammograms exhibited a rise upon increasing the sweeping rate, demonstrating the rapid kinetics of electrochemical reaction around the active electrode and increased electrode polarization.…”

Recently, transition metal dichalcogenides (TMDCs) have emerged as promising candidates as electrode materials for energy storage applications due to their remarkable physio-chemical properties. In the present work, a highly pure and crystalline tungsten diselenide (WSe 2 ) thin-film-based supercapacitive electrode has been successfully synthesized on a graphite substrate by using the DC magnetron sputtering method. Comprehensive characterization techniques including X-ray diffraction (XRD), Raman spectroscopy, Field emission-scanning electron microscopy (FE-SEM), and X-ray photoelectron spectroscopy (XPS) were employed to confirm the phase, elemental bonding, surface morphology, and chemical composition of the fabricated thin-film electrode, respectively. The sputtered WSe 2 thin-film electrode demonstrates an impressive increase in areal capacitance of almost 7.7 times when compared to the bare graphite substrate, with a measurement of 149.75 mF cm −2 . The electrode demonstrated excellent cyclic stability, retaining 86.15% of its capacitance even after 2000 cycles, showing the long-term usability and high potential of WSe 2 as an electrode. The capacitive performance of this symmetric supercapacitor device was carried out by using WSe 2 as a cathode as well as the anode with the 1 M Na 2 SO 4 electrolyte. Standing out in terms of electrochemical performance, the present symmetric supercapacitor executed a higher areal energy density and power density of 5.54 mWh cm −2 and 1197 mW cm −2 , respectively. This WSe 2 @graphite thin-film-based supercapacitive electrode with its superior electrochemical performance is believed to pave the way for the development of reliable and effective energy storage systems.
