Abstract:
Due to their unique structure, the metal sulfides are mechanically stable, have higher conductivities, and are frequently used in energy storage devices. Here, binder-free electrodes were designed by depositing the nickel zinc sulfide (NiZnS) incorporated with carbon nanotubes (CNTs) on the nickel foam (NF). X-ray diffraction (XRD) was used to describe the crystallinity of produced CNTs-NiZnS nanostructures, and morphological investigations were performed using field emission scanning electron microscopy (FESEM). According to the electrochemical measurements, the heating of electrolyte at 80 °C resulted in considerably enhanced specific capacitance of 1475 Cg −1 (50.85 F m −2 ) and 666 Cg −1 (13.77 F m −2 ) at 1 and 2 Ag −1 current density, correspondingly. Thus demonstrating a good capacity retention of 47% at 2 Ag −1 . The supercapattery (CNTs-NiZnS//AC) was designed with CNTs-NiZnS and AC, providing a specific charge capacity of 212 Cg −1 (at 2.0 Ag −1 ) along with energy density of 51 Wh-kg −1 at 820 W kg −1 power density. The stability of CNTs-NiZnS//AC was tested by subjecting it to 5000 successive cycles.
