摘要

Anodic nanomaterials based on ZnCo2O4 (ZCAN) were prepared via the ultrasonic electrodeposition technique, as a precursor to prefabricate high-performance materials to be used as anodes in Li-ion batteries (LIB). The impact of ultrasonic power on different properties of ZCAN, for instance, surface morphological features, crystal structure, phase composition, and electrochemical characteristics have also been investigated. The anodic nanomaterials based on ZnCo2O4 prepared at 600 W ultrasonic power have a subcrystalline size equivalent to 11.68 nm and feature a spinel surface morphology with a polyporous dendritic spore. Forevermore, the diffraction peak intensity of ZnCo2O4 steadily increased as the ultrasonic power (Up) rose from a value of 20–600 W. The emergence of discernible peaks in the spectra validates the existence of a spinel structure in the ZCAN specimens. Particularly, ZnCo2O4 anode nanomaterials prepared under the conditions of 600 W demonstrated exceptional electrochemical performance in comparison with the other samples. This superiority was evident in terms of the highest charge and discharge capacity with respective values of ~ 1176 mAh g−1 and ~ 1160 mAh g−1. The anodic materials also manifested the lowest electrical impedance value (35.65 Ω) and an optimal stability performance under a constant current density value of 150 mA g−1. Moreover, following a total of 1200 cycles, the coulombic efficiency of the as-fabricated nanomaterial stood at 98.6%, indicating its favorable cycling performance.
