Aqueous zinc-ion batteries(AZIBs)can be one of the most promising electrochemical energy storage devices for being non-flammable,low-cost,and sustainable.However,the challenges of AZIBs,including dendrite growth,hydrogen evolution,corrosion,and passivation of zinc anode during charging and discharging pro-cesses,must be overcome to achieve high cycling performance and stability in practical applications.In this work,we utilize a dual-func-tional organic additive cyclohexanedodecol(CHD)to firstly establish[Zn(H2O)5(CHD)]2+complex ion in an aqueous Zn electrolyte and secondly build a robust protection layer on the Zn surface to overcome these dilemmas.Systematic experiments and theoretical calculations are carried out to interpret the working mechanism of CHD.At a very low concentration of 0.1 mg mL-1 CHD,long-term reversible Zn plat-ing/stripping could be achieved up to 2200 h at 2 mA cm-2,1000 h at 5 mA cm-2,and 650 h at 10 mA cm-2 at the fixed capacity of 1 mAh cm-2.When matched with V2O5 cathode,the resultant AZIBs full cell with the CHD-modified electrolyte presents a high capacity of 175 mAh g-1 with the capacity retention of 92％after 2000 cycles under 2 A g-1.Such a performance could enable the commercialization of AZIBs for applications in grid energy storage and industrial energy storage.
