英文摘要：

Sodium-ion batteries （SIBs） as next-generation energy storage technology, especially for the large scale energy storage systems, have attracted recent attentions due to their abundant resource and low cost of sodium. It is important to develop high performance SIB cathodes and realize safe, efficient and commercialized applications. Vanadium oxides with various valence states, layered structures and compounds with multi-electron reaction exhibit a high storage capacity for SIBs. The design and optimization of vanadium oxide nanostructure can largely improve the electrochemical performance. This review summarizes recent development and their optimization strategies of vanadium oxide nanomaterials for SIBs. Combining with previous work by our group, we discuss the future directions in the application of vanadium oxides for high performance SIBs.
