Abstract: Aqueous Zn ion batteries are regarded as one of the most promising newgeneration electrochemical energy storage devices with a high specific capacity, high safety, and economic benefits. However, the direct utilization of Zn foils as metallic anodes is constrained by the problems of notorious Zn dendrite growth and severe corrosion. Recently, researchers have focused on inhibiting dendrite growth and reducing side reactions through electrolyte additives to obtain high-performance aqueous Zn ion batteries. Hence, this review first presents a general overview of aqueous Zn ion batteries and then systematically summarizes the mechanism of inhibition of dendrite growth and side reactions by electrolyte additives. Finally, suggestions for further development of electrolyte additive strategies in aqueous Zn ion batteries are presented.
