The exploitation of high-performance supercapacitors is crucial to promote energy storage technologies. Benefiting from the three-dimensional conductive micronanostructures and high specific capacity PPy@CuCo2S4@NF (polypyrrole/copper cobalt sulfide/nickel foam) composite electrode, this electrode exhibits a 1403.21 C g-1 at 1 A capacitance retention 85.79% after 10,000 cycles 10 g-1. assembled PPy@CuCo2S4@NF//AC aqueous hybrid supercapacitor (AHSC) reveals wide operating potential window 1.5 V achieves 322.52 86.84% 15,000 AHSC also power density 733.69 W kg-1 an 67.19 h kg-1, surpassing those previously reported spinel-based supercapacitors. Ex situ X-ray diffraction photoelectron spectroscopy results show that CuCo2S4 spinel structure changes CuS2 CoS2 cube structures, oxidation states Cu Co increase during charging discharging processes. Density functional theory calculations suggest superior conductivity for compared CuCo2O4, demonstrating has electrochemical performance. These findings attest considerable materials advanced applications.
