摘      要：With the low cost,excellent safety and high theoretical specific capacity,aqueous zinc-ion batteries(AZ-IBs)are considered as a potential rival for lithium-ion batteries to promote the sustainable development of large-scale energy storage ***,the notorious Zn dendrites and low Coulombic effi-ciency(CE)limit further development of AZIBs,due to the unstable electrochemical deposition/stripping behavior of Zn anode in aqueous zinc ion *** this review,critical issues and advances are summarized in electrolyte engineering *** strategies are focused on active water molecules during electrochemical process,including high-concentration electrolytes,ionic liquids,gel-polymer elec-trolytes and functional *** suppressed active water molecules,the solvation and de-solvation behavior of Zn^(2+)can be regulated,thereby modulating the electrochemical performance of Zn ***,the inherent problems of these strategies are discussed,and some promising directions are pro-vided on electrolytes engineering for high performance Zn anode in AZIBs.
