By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Materials Science. According to news reporting out of Kwangju, South Korea, by VerticalNews editors, research stated, "In this paper, ZnMn2O4 mesoscale tubular arrays on current collectors were successfully synthesized using a reactive template route combined with a postcalcination process through the shape-preserving conversion of ZnO nanorod arrays in aqueous solutions at room temperature. On the basis of the experimental analyses, including X-ray diffraction, Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy, a plausible formation mechanism of ZnM2O4 tubular arrays was proposed in which solid ZnO nanorods are gradually transformed to ZnMn2O4 tubules via a simple cation exchange process between Zn2+ and Mn2+, followed by a postannealing process."
Our news journalists obtained a quote from the research from Research Institute, "Moreover, the lithium storage properties of the as-prepared ZnMn2O4 tubular structures were investigated by applying the structures as an active electrode material without auxiliary additives. The ZnMn2O4 array electrodes showed an excellent discharge capacity of ca. 1198.3 mAh g(-1) on the first cycle and exhibited outstanding cycling durability, rate capability, and Coulombic efficiency."
According to the news editors, the research concluded: "These results indicate that the free-standing tubular array architectures of ZnMn2O4 prepared directly on the current collector can be powerful candidates for a highly reversible lithium storage electrode platform."
