Abstract Aqueous zinc (Zn) based batteries show great promise as energy storage devices, cost‐effectiveness, and intrinsic safety. However, the development of Zn‐based faces significant challenges, primarily stemming from poor electrochemical reversibility caused by dendrite growth, hydrogen generation, byproduct formation on Zn anode. In this study, valine (Val) is investigated an electrolyte additive to finely tune interface microenvironment, resulting in enhanced stability anode across a wide pH range, marking first time such approach has been explored. Val ions preferably adsorb onto active sites surface, enabling efficient isolation water SO 4 2− desolvated shell layer thus effectively inhibiting growth. The Zn||Zn symmetric cells are demonstrated with additives present remarkable cycling performance 5400 h. Furthermore, Zn||MnO 2 full exhibit stable operation for 5000 cycles at 3 A g −1 . Notably, also functions rechargeable alkaline cells, Zn||Ni 0.8 Co 0.1 Mn O operate durably temperature range.
