Boosting the energy storage performance with human hair-derived reduced keratin.

ABSTRACT: This investigation explores the potential use of keratin derived from human hair-a common bio-waste material-as a capacitive element that can deliver significant energy density in pseudocapacitors. The keratin was chemically reduced and extracted from untreated human male hair, producing a high-quality material. This method is related to a patent application (TR 2023/002929 B). The electrical conductivity of keratin has not been thoroughly examined and remains a topic of debate. While some studies suggest high conductivity under certain conditions, others point out inherent limitations. This study addresses these discrepancies by fabricating supercapacitor devices and evaluating their impedance and current-voltage characteristics under specific design parameters. The developed symmetric su
