Tuning Zn 2+ Deposition Kinetics towards Deep‐Reversible Zinc Metal Batteries with All‐Climate Adaptability

Abstract Uncontrollable Zn dendrites and severe hydrogen evolution reaction (HER) hamper the practical application of aqueous zinc‐metal batteries, which closely related to the deposition kinetics and thermodynamic stability of Zn anode. In this work, we returned to the classic perspectives of kinetics and thermodynamics, introducing a small amount of reduced glutathione (RGSH) to reshape the kinetic behavior of Zn 2+ deposition and increasing the thermodynamic energy barrier of HER. Specifically, the steric hindrance effect of RGSH tuned the electrochemical reduction kinetics to match Zn 2+ migration and increased the proportion of Zn 2+ in the bulk phase migration, thereby inducing dendrite‐free deposition…
