Abstract
Metal telluride-based nanomaterials have recently gained attention as promising candidates for enhancing the performance of electrodes in energy storage devices. In this study, Co-Zr-Te@CuO electrode materials engineered through strategic approach are introduced, involving the deposition of a Co-Zr metal-organic framework (MOF) on CuO nanowires, followed by a tellurization. This composite material demonstrates an expanded potential window of 1.2 V, making it potential electrode material for supercapacitor applications. Electrochemical evaluations reveal that the Co-Zr-Te@CuO electrode exhibits 576 C g-1, 1.8 times higher than Co-Zr-MOF@CuO. Furthermore, density functional theory (DFT) calculations confirm enhancements in conductivity and explains the synergistic effects present within the heterostructure. Hybrid supercapacitor (HSC) device achieves a peak energy density of 69.4 Wh kg-1 at a power density of 1.4 kW kg-1. This evidence of Co-Zr-Te@CuO effective electrode performance demonstrates its potential and robust stability for real-world energy storage applications.
The Co-Zr-Te@CuO electrode benefits from the rapid electron, which serve as oriented pathways for charge transfer. This composite material demonstrates an expanded potential window of 1.2 V, making it potential electrode materials for supercapacitor applications. image
