Metal zinc is considered one of the most potential anodes due to its energy density, safety, and cost-effectiveness. However, severe side reactions and unwanted dendrite growth during cycling make the stability of Zn metal anodes far from satisfactory. Herein, we rationally design a highly conductive carbon with abundant nitrogen and constructs it as a homogeneous layer on the Zn anode (denoted as CN-Zn) via the Langmuir-Blodgett method. CN-Zn not only features chemically stable in aqueous electrolytes with the corrosion-inhibition layer but also provides the nucleation sites for Zn²⁺ to induce the uniform deposition of Zn²⁺. With such a synergy effect, the CN-Zn||CN-Zn symmetrical cell can deliver a high capacity (5 mAh cm⁻²) and exhibit a prolonged reversible plating/stripping lifespan for more than 1300 h with an ultralow overpotential (24 mV) at 1 mAh cm^-2. Furthermore, the CN-Zn||MnO₂ pouch cell also achieves outstanding electrochemical performance with a discharge capacity of 116 mAh g^-1 at 5 mA, which provides high dependability of aqueous Zn batteries for commercial application.

由于其能量密度、安全性和成本效益，金属锌被认为是最具潜力的阳极之一。然而，循环过程中严重的副反应和不希望的枝晶生长使得锌金属负极的稳定性远不能令人满意。在此，我们合理地设计了一种富含氮的高导电碳，并通过 Langmuir-Blodgett 方法将其构建为锌负极（表示为 CN-Zn）上的均质层。CN-Zn不仅在具有腐蚀抑制层的水性电解质中具有化学稳定性，而且还为Zn ²⁺提供成核位点以诱导Zn 2+ 的均匀^沉积。有了这样的协同效应，CN-Zn||CN-Zn对称电池可以提供高容量（5 mAh cm ^-2) 并表现出超过 1300 小时的延长的可逆电镀/剥离寿命，在 1 mAh cm ^-2时具有超低的过电位 (24 mV) 。此外，CN-Zn||MnO ₂软包电池还具有出色的电化学性能，在 5 mA 时的放电容量为 116 mAh g ^-1，这为水系锌电池的商业应用提供了高可靠性。
