The reversibility and stability of Zn anode in aqueous electrolytes are largely limited by uncontrollable dendrite growth and parasitic reactions at the interface. Here, a monosodium glutamate (MSG) electrolyte additive is introduced to reconstruct the Zn anode/electrolyte interface and suppress Zn dendrite growth as well as H₂ evolution. The glutamate anions are preferentially adsorbed on the active sites for Zn corrosion and H₂ evolution so that these side reactions are largely suppressed. Moreover, the adsorbed glutamate anions can redistribute the Zn²⁺ ion flux and promote [Zn(H₂O)₆]²⁺ desolvation, leading to uniform Zn deposition at low overpotential. Accordingly, long-term cycling stability (> 1700 h at 5 mA cm⁻²/5 mA h cm⁻²) with a low voltage hysteresis (< 60 mV) in Zn||Zn symmetric cell is harvested. Even at a high current density of 9.11 mA cm⁻² with limited Zn supply (DOD_Zn = 80%), stable Zn deposition is achieved over 460 h. When coupled with NH₄V₄O₁₀ cathode, the assembled NH₄V₄O₁₀||Zn cell delivers higher capacity retention of 93.6% after 1000 cycles, compared to only 38.9% capacity retention in the absence of MSG.

锌负极在水性电解质中的可逆性和稳定性在很大程度上受限于不可控的枝晶生长和界面处的寄生反应。在这里，引入谷氨酸钠 (MSG) 电解质添加剂来重建锌负极/电解质界面并抑制锌枝晶生长和 H ₂释放。谷氨酸阴离子优先吸附在锌腐蚀和H ₂释放的活性位点上，从而大大抑制了这些副反应。此外，吸附的谷氨酸阴离子可以重新分配Zn ²⁺离子通量并促进[Zn(H ₂ O) ₆ ] ²⁺去溶剂化，导致在低过电位下均匀的 Zn 沉积。因此，在 Zn||Zn 对称电池中获得了具有低电压滞后 (< 60 mV)的长期循环稳定性 (> 1700 h at 5 mA cm ^-2 /5 mA h cm ^{-2 )。}即使在 9.11 mA cm ^-2的高电流密度和有限的 Zn 供应（DOD _Zn = 80%）下，也能在 460 小时内实现稳定的 Zn 沉积。当与 NH ₄ V ₄ O ₁₀阴极结合使用时，组装的 NH ₄ V ₄ O ₁₀ ||Zn 电池在 1000 次循环后可提供 93.6% 的更高容量保持率，而在没有 MSG 的情况下容量保持率仅为 38.9%。
