With the increasing dependence on high power equipment, there is an urgent need to develop advanced and sustainable energy systems. As one of the main energy storage devices, battery research should make great efforts to implement the sustainable development strategies on ecological, clean and environmentally friendly energy. Currently, aqueous zinc ion batteries (ZIBs) have gained much attention owing to their cheapness, abundant resources, high safety, and ecological friendliness. Nevertheless, ZIBs also have shortcomings with respect to the positive electrode. Therefore, the development of satisfactory positive electrode materials with structural stability and high capacity has become the focus of attention. In recent years, many vanadium‐based compounds have been strongly upheld for their advantages of safety and high theoretical capacity. In this paper, different energy storage mechanisms of vanadium‐based positive electrodes are summarized. Typical structures, such as layered and tunnel types, are particularly emphasized. Moreover, the comparison and analysis of electrochemical results of vanadium‐based compounds, including vanadium oxide and metal vanadate are focused. Finally, the strategies for improving aqueous ZIBs and development prospects are also discussed.
