Abstract: It is an important solution to solve energy storage problems by developing inexpensive and safe lithium-ion and sodium-ion batteries with superior performance. Vanadium-based electrode materials are promising electrode materials because of diversified chemical valences, open structures and high theoretical capacities. In the past few years, vanadium-based electrode materials such as oxides, sulfides, and phosphates have achieved a considerable development in the battery field, It is,  therefore, necessary to summarize their recent research progress. In this review, we particularly highlight the key challenges that are facing in the application of vanadium materials, such as low ion diffusion coefficient and poor structural stability. The possible solutions that are capable of addressing these challenges are analyzed from modification of active materials and their interaction with other materials. On the one hand, the enhancement of conductivity and ion diffusivity can be realized by valence tuning and heteroatoms doping, respectively. In addition, hierarchical assembly maximizes structural stability of materials during cycles, and 3D array engineering enable the improvement of power and energy density of battery simultaneously. We hope that this review can provide insights into the further development of vanadium-based electrode materials.
