Flower-like ZnCo2O4 nanowires: toward a high-performance anode material for Li-ion batteries

摘要: Rising interest in lightweight, thin, and flexible energy storage devices has led to numerous studies that aim fulfill the special needs of next-generation, high-performance electronics. In this study, flower-like ZnCo2O4 nanowires are fabricated by a facile hydrothermal method followed heat treatment air at 400 °C. The structures morphologies as-prepared characterized X-ray diffraction, scanning electron microscopy, transmission microscopy. data indicate as-synthesized approximately 2.5 μm length range from 50 nm 150 diameter. nanowire products evaluated as anode materials for lithium-ion battery application. structural features nanowires, including high coating uniformity, density, porous architecture, exert significant effect on electrochemical performance nanowires. discharge capacity can reach first 1430 mA h g−1 ∼900 after discharge–charge cycles current density 200 g−1, indicating its potential applications High is mainly attributed dense composed interconnected nanoparticles, which provide good electrolyte diffusion large electrode–electrolyte contact area while reducing volume change during charge–discharge process. electrode be used light up commercial emitting diodes.
