The primary focus of energy-storage device development is finding affordable ways to increase performance, activity, and stability. Here, we describe a one-pot hydrothermal synthesis of the composite containing zinc oxide (ZnO) for the supercapacitor electrode. Using Scanning electron microscopy (SEM), X-ray diffraction (XRD), Transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR), the physical–chemical and electrochemical characteristics of the produced materials were examined. At a current density of 1 A g−1, ZnO achieved a high specific capacitance of 184 F/g with 58.46% retention after 5000 cycles. According to the findings, the manufactured ZnO NPs showed promise supercapacitor electrode material.

摘要

The primary focus of energy-storage device development is finding affordable ways to increase performance, activity, and stability. Here, we describe a one-pot hydrothermal synthesis of the composite containing zinc oxide (ZnO) for the supercapacitor electrode. Using Scanning electron microscopy (SEM), X-ray diffraction (XRD), Transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR), the physical–chemical and electrochemical characteristics of the produced materials were examined. At a current density of 1 A g−1, ZnO achieved a high specific capacitance of 184 F/g with 58.46% retention after 5000 cycles. According to the findings, the manufactured ZnO NPs showed promise supercapacitor electrode material.
