Aqueous zinc-ion batteries(AZIBs)as green battery systems have attracted widespread attention in large-scale electrochemical energy storage devices,owing to their high safety,abundant Zn materials,high theoretica specific capacity and low redox potential.Nevertheless there are some thorny issues in AZIBs that hinder their practical application,such as low intrinsic electron conductivity,slow ion migration kinetics,zinc dendrites and side reactions.MXene-based materials with superior conductivity,large polar surface and abundant active sites can simultaneously serve as cathode materials,electrolyte additive and protection layer of anode to regulate redox reactions of AZIBs.Although various materials have been used to improve electrochemical performances of AZIBs there is a lack of in-depth discussion on the regulation mechanism of MXene-based materials for AZIBs.In this review,we elaborate the research progress of MXenebased materials in AZIBs,including their application in cathode materials and inhibition of zinc dendrites.Finally the future prospects and development directions of MXenebased materials that may improve performance of AZIBs are prospected. 展开更多

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,excellent 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 batteries,thus severely limiting their commercial application.In recent years,many more researches have been conducted 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 mechanism 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. 展开更多
