Zinc ion batteries have gotten increasing attention as a potential candidate for lithium-ion batteries, due to their high specific capacity (820 mAh·g⁻¹), energy density, and safety. Inevitably, dendrite and corrosion create some trouble for this system. Herein, an integrated Zn electrode coated by Zn-Al metal oxides prepared by a simple spin-coating method was utilized to increase the rechargeability for aqueous zinc ion batteries. By coating the Zn anode with an artificial electrolyte interface, the wettability of Zn anodes was improved and impedance was reduced. The coating suppressed not only the appearance of dendrite but also the formation of corrosion products. The symmetrical cells with coating have a low overpotential (43 mV) and an excellent life span. Meanwhile, the applied full batteries exhibit an improved capacity retention rate (86.67% after 120 cycles), great rate performance and low apparent activation energy (24.6 KJ·mol⁻¹). The simple production methods and superior corrosion suppression effects provide new ideas for the anode protection of aqueous system batteries.

锌离子电池因其高比容量（820 mAh·g ^-1)、能量密度和安全性。不可避免地，枝晶和腐蚀会给这个系统带来一些麻烦。在此，通过简单的旋涂方法制备的由 Zn-Al 金属氧化物包覆的集成 Zn 电极被用于提高水系锌离子电池的可充电性。通过在锌阳极上涂覆人工电解质界面，提高了锌阳极的润湿性并降低了阻抗。该涂层不仅抑制了枝晶的出现，而且抑制了腐蚀产物的形成。带涂层的对称电池具有低过电位 (43 mV) 和出色的使用寿命。同时，所应用的全电池表现出更高的容量保持率（120次循环后为86.67%）、良好的倍率性能和较低的表观活化能（24.6 KJ·mol ^-1）。简单的生产方法和优越的缓蚀效果为水系电池的负极保护提供了新思路。
