In the past few decades, supercapacitors (SCs) have emerged as good and reliable energy storage devices due to their impressive power density, better charge-discharge rates, high cycling stability. The main components of a supercapacitor are its electrode design composition. Many compositions tested for preparations, which can provide performance. Still, research is widely progressing in developing optimum high-performance electrodes. Metal chalcogenides recently gained lot interest application intriguing physical chemical properties, unique crystal structures, tuneable interlayer spacings, broad oxidation states,

Abstract Dysprosium‐modified tungsten oxide/carbon nanofibers (Dy‐WO 3 /PCNFs) are fabricated via electrospinning combined with high‐temperature calcination to synthesize a flexible, self‐supporting electrode material that does not require conductive agent or binder. XRD and TEM analyses showed introducing dysprosium promoted the preferential growth of WO crystals along preponderance crystal planes involved in electrochemical reaction, enhancing exposure (002) (200) planes. Furthermore, DFT calculations demonstrated incorporation Dy resulted enhanced adsorption Dy‐WO by PCNFs, an energy −1.21 eV. The Bader charge results indicate transfer 1.70 |e| from PCNFs . demonstrate strong facilitates adsorption/desorption, which contributes enhances storage capacity. prepared /PCNFs exhibited high specific capacitance (557.28 F g −1 at 0.5 A ). Supercapacitors assembled as positive CNFs negative have density (29.8 Wh kg power 363.48 W This study demonstrates successful synthesis exceptional properties offers significant insights into design application flexible electrodes incorporating modulate surface
