In recent years, zinc‐ion batteries (ZIBs) with near neutral (pH ≈ 4–6) Zn2+‐containing aqueous electrolyte have received extensive research due to their advantages of high safety, low production cost, suitable anode zinc, and environmental friendliness, etc. At present, one of the key challenges of aqueous ZIBs is the development of cathode materials with stable structure, rapid kinetics, and high capacity, etc. Compared with other cathode materials, V2O5 has an important potential application because of its high theoretical specific capacity (589 mA h g−1) based on two electron transfers, relatively low production cost, and suitable layered structure that facilitates zinc ion insertion/extraction. Herein, the following sections are proposed: 1) An understanding of the structure and energy storage mechanism of V2O5; 2) The recent development on the aqueous Zn/V2O5 battery from properties of V2O5 cathode and composition optimization of battery structure; 3) The application of V2O5 cathode in flexible ZIBs; and 4) The outlook and development trends in the future.
