Herein, a high-modulus, charge-rich interfacial layer is constructed through electrostatic coupling of poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) with polyaminopropyl biguanide (PB) to stabilize Zn anodes. The coupled interfacial layer synergistically integrates anion–cation regulation with enhanced mechanical robustness, accelerating Zn²⁺ desolvation, regulating ion flux, and suppressing side reactions. Meanwhile, the high-modulus yet tough interfacial layer effectively mitigates dendrite growth and buffers volume fluctuations during repeated Zn plating/stripping. As a result, the symmetric cells deliver an ultralong lifespan of over 2200 h at 1.0 mA cm^–2 and 1.0 mAh cm^–2, and maintain stable operation for over 800 h at 20.0 mA cm^–2 with 10.0 mAh cm^–2. Zn||Cu cells achieve highly reversible plating/stripping over 2000 cycles, and the Zn||NaV₃O₈ full cells demonstrate excellent rate capability and long-term cycling over 3500 cycles. This work provides a promising strategy for enhancing the anode stability of high-performance aqueous zinc batteries. 2026-09-29T00:00:00Z Text Journal contribution 10.1021/jacs.6c14681.s001 https://figshare.com/articles/journal_contribution/Electrostatically_Coupled_High-Modulus_Interphase_with_Synergistic_Anion_Cation_Regulation_for_Stable_Zn_Anodes/34025338 CC BY-NC 4.0
