摘要
Abstract Aqueous zinc‐ion batteries (ZIBs) are promising candidates for the next‐generation high‐energy storage devices, owing to their resource availability, low cost, eco‐friendliness, and high safety. The zinc (Zn) metal anode in a suitable battery system, including an electrolyte and a high‐performance cathode electrode, can deliver an excellent electrochemical performance. However, several obstacles must be overcome to utilize aqueous ZIBs. Among these, Zn dendrite growth, corrosion, and side reactions severely impair the performance of rechargeable ZIBs. To deal with these issues, a profound understanding of the mechanism of the matter occurring in electrochemical cycles is essential to thoroughly solve the challenges. Instead of focusing solely on techniques for improving the performance of Zn metal anodes, this review delves into and summarizes the causes of side reactions and dendrite formation, thereby establishing a logical system of methodologies for improving the electrochemical performance of mild aqueous ZIBs. The correlation between the Zn metal anode, aqueous electrolyte, separators and the performance of ZIBs is also discussed in detail. There is also a brief perspective on the future development of Zn metal anodes in aqueous solutions. This study sheds a light on the challenges associated with the construction of high‐performance ZIBs, which will significantly aid in their practical implementation.
