Molecular Damping Effect of Trace Additives Enhances Zinc Anode Stability Under High Depth of Discharge.

ABSTRACT: Resolving the severe issues such as electric field distortion, dendritic zinc growth, and uneven zinc deposition under high depths of discharge (DOD) has become a significant hurdle of the aqueous zinc-ion batteries (ZIBs). To address these challenges, an interfacial regulation strategy is proposed based on the molecular damping effect, in which a trace amount of weakly adsorbing additive is employed to stabilize the Zn anode interface by mitigating energy shocks and ionic disturbances induced by electric field fluctuations. Trace perfluorinated PSVE (erfluoro-3,6-dioxa-4-methyloct-7-enesulphonyl fluoride) is introduced to the traditional ZnSO₄ electrolyte to optimize Zn deposition behavior on the zinc anode. Thus, the Zn//Zn symmetric batteries exhibit a prolonged cycling lifes
