The electrochemical supercapacitor has shown to be a reliable and innovative type of energy storage technology over the years. Recent research that CoWO4 is potential material for applications because its unique characteristics, which make it suitable storage. particles are synthesized using hydrothermal method with PVP as capping agent, followed by 2-hour post-heat treatment at 300 ℃. powder was characterized through X-ray diffraction (XRD), scanning electron microscopy, Raman spectroscopy, techniques. XRD analysis revealed crystalline nature sample. indexed peaks conform monoclinic crystal framework space group P2/c. SEM image indicates significant structural agglomeration in material. electrode high specific capacitance 135 F/g 10 mV/s 1 M KOH electrolyte between − 0.15 V 0.6 window. Galvanostatic charge-discharge measurements reveal 115 0.23 A/g current density retains 96.12% even after 1000 cycles Moreover, improved window observed during cyclic voltammetry measurements.
