Smart Electrolyte Additives Toward Durable Aqueous Zinc‐Ion Batteries

Abstract Zinc‐ion batteries (ZIBs) have emerged as a promising class of next‐generation electrochemical energy storage devices due to their inherent advantages, including high safety, low cost, large theoretical capacity, and the abundance of zinc resources. However, their practical deployment remains hindered by critical challenges, such as cathodic materials dissolution, hydrogen evolution side reactions, and uncontrolled zinc dendrite growth. As the medium bridging the anode and cathode, electrolytes play a pivotal role in addressing these issues, particularly through the strategy of incorporating electrolyte additives. This review highlights the key limitations of current aqueous ZIBs, emphasizes the decisive influence of solvation structures on both interfacial and bulk behaviors, and summarizes recent advances in electrolyte additives design. Finally, forward‐looking perspectives on electrolyte engineering are provided to accelerate the practical development of high‐performance aqueous ZIBs.
