Novel Ag2Cu2O3 nanorods as stable anode material for lithium-ion battery

Abstract

In this research novel Ag₂Cu₂O₃ nanorods was prepared, for lithium-ion battery as anode, using facile co-precipitation method with four different stirring time and correspondingly Ag₂Cu₂O₃ named ACO – 30 M, ACO – 12 H, ACO – 24 H, and ACO – 36 H. Field Emission Scanning Electron Microscopy (FESEM) and High-Resolution Transmission Electron Microscopy (HRTEM) analyze surface and morphology, while X-ray Diffraction (XRD) examines structural properties. Compositional analysis is carried out using X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The electrochemical analysis is evaluated by cyclic stability, rate capability, discharge/charge capacity, electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV). The ACO – 24 H nanomaterial demonstrates an initial discharge capacity of 943 mAh g⁻¹ at a current density of 50 mA g⁻¹. Among the four materials tested, ACO – 24 H shows superior cycling performance, with a discharge capacity of 174 mAh g⁻¹ at 200 mA g⁻¹ after 1003 cycles. In comparison, ACO – 30 M, ACO – 12 H, and ACO – 36 H exhibit capacities of 134 mAh g⁻¹, 91 mAh g⁻¹, and 43 mAh g⁻¹, respectively, under the same conditions. This study suggests that ACO – 24 H is a promising anode material for lithium-ion battery applications.
