The material has been characterised via infrared (FTIR) spectroscopy, electron microscopy (FESEM), and X-ray diffraction (XRD). The FTIR spectrum reveals a peak at 1126 cm^-1, which corresponds to the S-O bending mode, and a peak at 663 cm^-1, which represents sulphide stretching. According to XRD analysis, cobalt sulphide formed with the CoS1.097 configuration. FESEM study reveals that cobalt sulphide hexagonal sheets with a thickness of less than 100 nm have been prepared that are further arranged in a floral pattern. Cobalt and sulphide concentrations were found to be proportional in EDX analyses. Further, Electrochemical testing was performed with a two-electrode setup, 6M KOH as the electrolyte, and various current collectors (including nickel foam and aluminium foil). The galvanostatic charge-discharge characteristics and capacitance values have been compared using impedance spectroscopy and other techniques. Details of the analysis are presented. https://www.materialsciencejournal.org/vol19no3/evaluation-of-electrochemical-performance-of-cobalt-sulphide-on-various-current-collectors/ Cobalt sulphide Characterizations Electrode design Hydrothermal Supercapacitor
