Uncontrolled dendrite growth and side reactions pose obstacles to the practical implementation of aqueous zinc-ion batteries (AZIBs). Here, a cost-effective trace additive, benzohydroxamic acid (BHA), is introduced into a 2.0 M ZnSO₄ electrolyte to form a spontaneous anode-molecule interface. Notably, the BHA molecule has strong interactions with Zn²⁺ ions and can absorb on the anode surface, promoting dynamic transmission and deposition and displaying a role in suppressing side reactions. The impressive cycling stability of the Zn||Zn symmetric cell exceeds 1,400 h at 5.0 mA cm⁻² and 5.0 mAh cm⁻², achieved by incorporating a trace BHA additive. Furthermore, it endures over 600 h, even at a relatively high depth of discharge (DOD) of 62.6 %. Additionally, under practical conditions (N/P = 3.83), the assembled Zn||I₂/AC full cell with BHA additives displays stable cycling for 800 cycles at 2.0 A g⁻¹. This innovative strategy provides a cost-effective approach for achieving AZIBs with an extended lifespan.

不受控制的枝晶生长和副反应给水性锌离子电池（AZIB）的实际应用带来了障碍。在此，将一种经济有效的痕量添加剂苯并异羟肟酸（BHA）引入2.0 M ZnSO ₄电解质中以形成自发的阳极-分子界面。值得注意的是，BHA分子与Zn ²⁺离子有很强的相互作用，可以吸附在阳极表面，促进动态传输和沉积，并表现出抑制副反应的作用。 Zn||Zn 对称电池在 5.0 mA cm ^-2和 5.0 mAh cm ^-2下的循环稳定性令人印象深刻，超过 1,400 小时，这是通过掺入微量 BHA 添加剂实现的。此外，即使在 62.6% 的相对高放电深度 (DOD) 下，它也能持续超过 600 小时。此外，在实际条件下（N/ P = 3.83），使用BHA添加剂组装的Zn||I _{2 /AC全电池在2.0 A g} ^-1下表现出稳定的循环800次。这一创新策略为实现 AZIB 的延长寿命提供了一种经济有效的方法。
