Inspired by the nanostructured graphene-based membranes for ionic sieving, an ion-oriented interface of few-layer graphene (FLG) was rationally constructed to achieve long-life zinc (Zn) metal anode. The ion-oriented interface increased the nucleation sites and inhibited localized dendrite growth, which aided the uniform transmission of Zn ions. Moreover, the fewer oxygen-containing functional groups on the FLG surface demonstrated a lower energy barrier of ion transport and a stronger Zn ion-regulating function. The FLG@Zn anode exhibited a much larger capacity with significant stability in the cycling behavior against MnO₂ cathode compared to the pristine Zn anode. Specifically, a nearly 97% capacity retention was achieved for FLG@Zn/MnO₂ battery after 5000 cycles at 10 A·g^–1. Our work provides a novel approach to the fabrication of high-performance Zn anode for ultra-stable aqueous batteries.

受用于离子筛分的纳米结构石墨烯基膜的启发，合理构建了少层石墨烯（FLG）的离子取向界面，以实现长寿命的锌（Zn）金属阳极。离子取向界面增加了成核位点并抑制了局部枝晶生长，这有助于锌离子的均匀传输。此外，FLG 表面含氧官能团越少，离子传输的能垒越低，Zn 离子调节功能越强。与原始锌负极相比，FLG@Zn 负极在对 MnO ₂正极的循环行为中表现出更大的容量和显着的稳定性。具体而言，FLG@Zn/MnO ₂电池在10 A·g下循环5000次后，容量保持率接近97%^–1 . 我们的工作为制备用于超稳定水系电池的高性能锌负极提供了一种新方法。
