In Situ Constructing Metal–Organic Complex Interface Layer Using Biomolecule Enabling Stabilize Zn Anode

Abstract Aqueous zinc‐ion batteries (ZIBs) are considered as a promising candidate for next‐generation large‐scale energy storage due to their high safety, low cost, and eco‐friendliness. Unfortunately, commercialization of ZIBs is severely hindered owing to rampant dendrite growth and detrimental side reactions on the Zn anode. Herein, inspired by the metal–organic complex interphase strategy, the authors apply adenosine triphosphate (ATP) to in situ construct a multifunctional film on the metal Zn surface (marked as ATP@Zn) by a facile etching method. The ATP‐induced interfacial layer enhances lipophilicity, promoting uniform Zn²⁺ flux and further homogenizing Zn deposition. Meanwhile, the functional interlayer improves the anticorrosion ability of the Zn anode, effectively suppressing corrosion and hydrogen evolution. Consequently, the as‐prepared ATP@Zn anode in the symmetric cell exhibits eminent plating/stripping reversibility for over 2800 h at 5.0 mA cm⁻² and 1 mAh cm⁻². Furthermore, the assembled ATP@Zn||MnO₂ full cells are investigated to evaluate practical feasibilities. This work provides an efficient and simple strategy to prepare stabilized Zn anode toward high‐performance ZIBs.
