Description
With the growing emphasis laid on the research related to energy storage systems, the need for cost-effective and efficient materials is quintessential. The present work reports a comprehensive study and a promising strategy to enhance the electrochemical behaviour of Carbon Black derived from waste tires by the incorporation of heteroatoms such as Nitrogen and Sulfur into the system. The study investigates the electrochemical performance of Carbon Black with single doping, and further examines the enhanced performance with co-doping. While the Nitrogen-doped Carbon Black exhibits a specific capacitance of 97.63F/g, the Sulfur doped Carbon Black exhibits 141.8F/g and the co-doped Carbon Black exhibits an enhanced specific capacitance of 233F/g at a current density of 1 A/g in the two-electrode system. A significant improvement in the specific surface area is achieved in the materials with post-doping techniques. Furthermore, the co-doped Carbon Black provides superior electrochemical behaviour with sustained energy density of 30Wh/kg even at a higher power density of 5.6kW/kg with an improved cyclic stability of 91% over 5000 cycles. Thus, effective valorization of Carbon Black recovered from waste tires enables the development of efficient and affordable electrode material for the fabrication of supercapacitors. 2025 Elsevier B.V.
