Aqueous zinc-ion batteries (AZIBs) are promising candidates for next-generation energy storage systems. However, the practical implementation is hindered by challenges associated with zinc (Zn) dendrite growth and parasitic side reactions. Here, we designed a self-assembled monolayer (SAM) using theanine (CA) to modify Zn anode. As expected, CA can strongly interact substrate through carboxyl groups, forming compact uniform SAM. The amino amide functional groups of exhibit high affinity, effectively regulating Zn2+ flux achieving deposition. ultrathin interface provided acts as barrier water molecules, thereby suppressing hydrogen evolution reactions (HER) minimizing formation undesirable byproducts. result, anodes protected demonstrate exceptional durability, operating over 2000 h at current density 5 mA cm-2 an areal capacity 2 mAh cm-2. Additionally, full cells paired NH4V4O10 cathodes also superior reaction reversibility retention. CA-based SAM holds promise overcoming critical faced in anode advancing development stable efficient AZIBs.
