Abstract

Abstract: Constructing hollow nanostructures is attractive for both fundamental research and practical applications. However, how to prepare hollow nanostructures in a simple, scalable, and cost‐effective way still remains a great challenge. In this study, for the first time, the anodization technique is applied to construct hollow nanostructures. Specifically, hollow nanospheres of SnS/SnOx with a hierarchical porous structure are self‐assembled directly on the Sn substrate, via a convenient one‐step anodization method. When applied for sodium‐ion batteries, the thus fabricated SnS/SnO x hollow nanospheres on the substrate readily serve as a binder‐free electrode, delivering remarkably high cycling stability and rate capability. Abstract : Hierarchical SnS/SnO x hollow nanospheres fabricated via a simple, scalable, and cost‐effective anodization method for high‐performance sodium storage are reported.
