Abstract
Electrode materials are crucial to the electrochemical performance of supercapacitors. FeS2, a transition metal dichalcogenide (TMD), offers affordability and efficient redox reactions, making it a promising candidate. This study addresses the low conductivity of FeS2 electrodes by introducing copper doping, significantly enhancing specific capacitance by nearly 50%, from 61 F g⁻¹ to 122 F g⁻¹. The stability of Cu-doped FeS2 is maintained over 200 cycles, presenting a viable solution for pseudocapacitor electrode development.
