Abstract

Metallic Zn anode is receiving increased attention due to its high safety and low cost. However, its practical application is limited by the dendritic growth and corrosive reaction. Herein, the electrochemical stripping/plating behaviour of metallic Zn was studied in the hybrid aqueous/organic electrolyte composed of 2 M Zn(OTF)₂in polyethylene glycol (PEG)-H2O solvent with different volume ratios of PEG content ranging from 0 vol% to 50 vol%, in which the water activity decreased through altering its hydrogen-bonding structure with PEG. An optimized PEG content of 50 vol% enabled a dendrite-free Zn anode morphology during repeated plating/stripping processes. The mechanism of morphology was analyzed by scanning electron microscopy, cyclic voltammetry, and X-ray diffraction. And the corrosion-suppressive reaction was analyzed by linear polarization curves. Finally, the optimized Zn anode showed a high reversibility of stripping/plating behavior (1000 h), which contributed to the suppressed dendritic growth and corrosive reaction.
