In situ observation of the sodiation process in CuO nanowires

Abstract

We observed the dynamic evolution of the morphology and phase transformations of CuO nanowires during sodiation using in situ transmission electron microscopy. These results will facilitate our fundamental understanding of the sodiation mechanism of CuO nanostructures used as electrode materials in sodium ion batteries.
