| Summary: | <p dir="ltr">For practical uses, there has been a lot of interest in simple, inexpensive, and efficient synthesis of materials for supercapacitor applications. Pure and cobalt-doped zinc sulfide (Co-doped ZnS) powder samples were synthesized in this study using a straightforward co-precipitation process, and their electrochemical performance was examined. It was observed that, at a scan rate of 10 mV s<sup>−1</sup>, pure ZnS has a specific capacitance of only 460.7 F g<sup>−1</sup>; however, the Co-doping in ZnS increases it to 947.8 F g−1 for the 5% Co-doped sample, Co (0.05): ZnS. The results suggest that Co-doping in ZnS increases the kinetics and rate of redox processes. The increase in electrochemical active sites brought about by integrating Co into ZnS increases the surface area and results in the sample's capacity for storage. The encouraging findings increase the likelihood of elemental doping with other transition metal elements to increase the energy storage capability of earth-abundant ZnS samples.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Electronic Materials<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s11664-024-11535-6" target="_blank">https://dx.doi.org/10.1007/s11664-024-11535-6</a></p> |
