Zinc‐ion hybrid supercapacitors (ZIHSCs) represent a promising frontier in high‐performance energy storage, offering greater density characteristic shown by batteries alongside high power yield and extended life of supercapacitors. Carbon materials, due to their inexpensiveness, abundance, excellent conductivity, have been cathode choices for ZIHSCs. However, the application electrospun carbon nanofibers as cathodes ZIHSCs remains relatively unexplored. This study describes synthesis porous N‐doped (NC)‐carbon (NC‐CNFs) through carbonization‐activation pathway. The NC‐CNFs achieves specific surface area (SSA) 2426.6 m 2 g −1 capacity 173.5 mAhg at 0.1 Ag ZIHSC setup. A maximum (ED) (PD) 138.8 Wh kg 7998.9 W , respectively is also obtained. After 10 000 charge‐discharge cycles, device retains 91.7% initial capacitance. Additionally, charge storage performances symmetric supercapacitor (SC) ZIHSC, made NC‐CNFs, are compared prove superiority over SC. highlights that incorporating NC into nanofibers, with potassium hydroxide (KOH) activation, yields material an optimal 1D morphology, large SSA, optimized nanofiber diameter, efficient heteroatom doping, leading electrochemical performance.

Abstract In the contemporary age, there is a growing need for innovative energy storage solutions that integrate crucial features of supercapacitors and rechargeable batteries to meet evolving requirements. Herein, we used hydrothermal method synthesize binary composite electrode material. The addition ZnO as doping material significantly enhances specific capacity cobalt niobium sulphide (CoNbS) from 538.16 C g −1 912.62 due its high conductivity presence redox‐active sites. We have also developed supercapattery (CoNbS@ZnO//activated carbon [AC]), which has demonstrated outstanding performance with remarkable 325.92 at current density 1.5 A . Furthermore, device shows improved power densities, measuring 35 Wh/kg 2397 W/kg, respectively. After 5000 galvanostatic charging discharging (GCD) cycles, columbic efficiency (90%) retention (83%). Additionally, CoNbS@ZnO//AC hybrid an electrochemical sensor glucose detection. showed sensitivity against detected up small value. synthesis nanomaterials opens new opportunities create high‐performance related systems.
