Well-dispersed NiFeS2@Cu2S heterojunction nanorods as high energy density electrode for supercapacitors
Source abstract
Abstract
Transition metal sulfide heterostructures have demonstrated significant potential in enhancing the performance and cycling stability of supercapacitors due to their adjustable electronic structure. In this study, we synthesized an integrated electrode by constructing NiFeS 2@Cu 2S heterostructure nanorods onto a copper foam (CF) substrate. The heterostructure displays a crucial role in improving the electrochemical properties of the NiFeS 2@Cu 2S electrode, which exhibits a high specific capacity of 588 mAh g −1 at a current density of 1 A g −1. Moreover, The assembled CF@NiFeS 2@Cu 2S //CF@AC asymmetric supercapacitor (ASC) delivers an impressive energy density of 68.6 Wh kg −1 at a power density of 800 W kg −1. This work provides a novel strategy to design and construct highly efficient electrode materials for energy storage applications.
