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. © 2025 Elsevier B.V.CoprecipitationCyclic voltammetryElectrochemical impedance spectroscopyField emission microscopesHigh resolution transmission electron microscopyNanorodsAnode material for lithium ion batteriesCo-precipitationCoprecipitation methodField emission scanning electron microscopyHigh-resolution transmission electron microscopyIon batteriesLithium ionsNanorod/nanomaterialSilver-copper oxidesStirring timeX ray photoelectron spectroscopy
