New insights on (V10O28)6−-based electrode materials for energy storage: a brief review

Progress in humanity has intensified the demand for efficient and renewable energy storage, which warrants the development of advanced rechargeable batteries such as lithium-ion batteries (LIBs), sodium-ion batteries (SIBs), zinc-ion batteries (ZIBs), and lithium-sulfur batteries (Li–S batteries). Nevertheless, these batteries still suffer from certain limitations, such as the insufficient capacity and inferior stability in their electrode materials. Therefore, developing a feasible electrode material for Li/Na/Zn ion storage represents a critical challenge. Recently, polyoxovanadates (POVs) materials, particularly decavanadate anion (V 10 O 28 ) 6− clusters, have attracted considerate attention as promising battery electrodes, due to their rich multi-electron redox process, high structural stability, simple preparation process, and abundant ligand environment. In this review, we provide an overview of the research progress of (V 10 O 28 ) 6− -based materials in various metal-ion battery systems, including LIBs, SIBs, ZIBs, and Li–S batteries. We also discuss the underlying challenges associated with this type of materials, and we provide alternative strategies to overcome these issues. This review aims to facilitate the research and development of the next-generation (V 10 O 28 ) 6− -based battery materials. Graphic abstract
