Overview

Randomized trial demonstrates enhanced supercapacitor performance with nickel-doped ZnS electrodes, suggesting cost-effective applications.

Key Points

  • This research aims to enhance the electrochemical performance of zinc sulfide electrodes through nickel doping.
  • Utilized a chemical co-precipitation method to synthesize ZnS samples with varying nickel concentrations (1%, 3%, 5%).
  • Conducted electrochemical analyses using a three-electrode setup to assess performance.
  • Analyzed structural and morphological properties to confirm nickel incorporation into the ZnS lattice.
  • The Ni 3%-ZnS sample achieved a specific capacitance of 893.5 F/g at 10 mV/s, compared to 460.7 F/g for undoped ZnS.
  • Significant improvements in ion transport and reduced charge-transfer resistance were observed.
  • The Ni 3%-ZnS electrode retained high capacitance after 1000 cycles, indicating excellent cyclic stability.
