Aqueous zinc-ion batteries (AZIBs) have emerged as one of the most promising energy storage technologies due to their high safety and cost-effectiveness. However, several challenges associated with the Zn metal anode, such as dendrite growth, corrosion, and hydrogen evolution reaction (HER), have hindered further applications of AZIBs. Herein, maltose (MT) is used as a functional electrolyte additive to protect the Zn metal electrode during the interface deposition process. The additive can effectively affect the interface of Zn metal, suppressing HER and corrosion reactions. Moreover, it facilitates the uniform deposition of Zn by inducing Zn to form a stable (100) crystal plane. As a result, the symmetric cell exhibited stable cycling performance for 2000 h at a current density of 2 mA cm, and the Zn||NHVO full cell maintained steady cycling for 1000 cycles at 2 A g. This study provides an approach to achieve uniform Zn deposition through additives.
水系锌离子电池（AZIBs）因其高安全性和成本效益而成为最具前景的储能技术之一。然而，与锌金属负极相关的几个挑战，如枝晶生长、腐蚀和析氢反应（HER），阻碍了AZIBs的进一步应用。在此，麦芽糖（MT）被用作功能性电解质添加剂，以在界面沉积过程中保护锌金属电极。该添加剂可以有效影响锌金属的界面，抑制HER和腐蚀反应。此外，它通过诱导锌形成稳定的（100）晶面促进锌的均匀沉积。结果，对称电池在2 mA cm的电流密度下表现出2000 h的稳定循环性能，并且Zn||NHVO全电池在2 A g下保持1000次循环的稳定循环。本研究提供了一种通过添加剂实现锌均匀沉积的方法。
