Abstract In this study, transition metal sulfide‐based binder‐free hybrid electrodes were grown in‐situ on Ni foam using hydrothermal method. However, it still remains a challenge for designing heterostructure with sufficient electroactive sites to improve electrochemical performance. Herein, effects of CNF@NSNCS composites investigated developing high‐performance, low‐cost supercapacitors. By avoiding the use additive binding polymers, purity was enhanced, resulting in excellent behavior. The prepared composite electrode exhibited an ultrahigh specific capacitance 2739 F/g at current density 1 A/g, superior retention charge‐discharge cycle stability 100 % over continuous 14,000 cycles 10 A/g. Furthermore, asymmetric supercapacitor (ASC) assembled as positive and Activated carbon (AC) negative electrode. devices demonstrated performance, delivering high energy 77.5 Wh/kg power 748.4 W/kg. This work may contribute advancing development low‐cost, high‐performance storage applications next generation portable electronic devices.
