As a new type of green battery system,aqueous zinc-ion batteries(AZIBs)have gradually become a research hotspot due to their low cost,high safety,excel-lent stability,high theoretical capacity(820 mAh·g-1)of zinc anode,and low redox potential(-0.76 V vs.standard hydrogen electrode(SHE)).AZIBs have been expected to be an alternative to lithium-ion batteries for large-scale commercial energy storage applications.Unfortunately,they are facing thorny issues such as degradation of cycling performance,zinc dendrites,and side reactions.At the same time,these problems cause short cycling life of bat-teries,thus severely limiting their commercial application.In recent years,many more researches have been con-ducted on the modification of anode and cathode materials of AZIBs,but there is a lack of in-depth discussion on the characteristics and mechanism of electrolyte additives.In this review,we will make a systematic summary of the current problems with two electrodes in AZIBs,as well as the types and functions of electrolyte additives.Moreover,we further systematically describe the modulation mecha-nism of electrolyte additives in the performance of the cathode and anode.The prospects and development directions of additive modulation strategies for AZIBs electrolytes are prospected.
