Large-scale synthesis of Ag1.8Mn8O16 nanorods and their electrochemical lithium-storage properties

Ag1.8Mn8O16 nanorods have been synthesized on a large scale by a facile hydrothermal route. The effects of experimental conditions including reaction time and reactant concentration on the phase and morphology of the final products were investigated systematically. The products were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy-dispersive X-ray (EDX) spectroscopy. Electrochemical lithium-storage capabilities of the as-formed nanostructured Ag1.8Mn8O16 were also evaluated. Interestingly, the as-formed Ag1.8Mn8O16 nanorods possess the unique one-dimensional structure and in situ silver loading, which are beneficial features for electrochemical lithium-storage applications. The results suggest their potential use as cathode materials for lithium-ion batteries.
