Many optimization strategies have been employed to stabilize zinc anodes of zinc-ion batteries (ZIBs). Although these commonly used strategies can improve anode performance, they simultaneously induce specific issues. In this study, through the combination of structural design, interface modification, and electrolyte optimization, an ‘all-in-one’ (AIO) electrode was developed. Compared to the three-dimensional (3D) anode in routine liquid electrolytes, the new AIO electrode can greatly suppress gas evolution and the occurrence of side reactions induced by active water molecules, while retaining the merits of a 3D anode. Moreover, the integrated AIO strategy achieves a sufficient electrode/electrolyte interface contact area, so that the electrode can promote electron/ion transfer, and ensure a fast and complete redox reaction. As a result, it achieves excellent shelving-restoring ability (60 hours, four times) and 1200 cycles of long-term stability without apparent polarization. When paired with two common cathode materials used in ZIBs (α-MnO2 and NH4V4O10), full batteries with the AIO electrode demonstrate high capacity and good stability. The strategy of the ‘all-in-one’ architectural design is enlightened to solve the issues of zinc anodes in advanced Zn-based batteries.

用于稳定高性能锌离子电池的锌阳极的一体化“一体化”策略

已采用许多优化策略来稳定锌离子电池 (ZIB) 的锌阳极。尽管这些常用策略可以提高阳极性能，但它们同时会引发特定问题。在这项研究中，通过结合结构设计、界面改性和电解质优化，开发了一种“一体式”（AIO）电极。与常规液体电解质中的三维（3D）阳极相比，新型AIO电极可以极大地抑制活性水分子引起的气体逸出和副反应的发生，同时保留了3D阳极的优点。此外，集成的AIO策略实现了足够的电极/电解质界面接触面积，从而使电极能够促进电子/离子的转移，确保氧化还原反应快速而完全。因此，它具有出色的搁架恢复能力（60小时，四次）和1200次长期稳定性循环，无明显极化。当与 ZIB 中使用的两种常用正极材料（α-MnO2 和 NH4V4O10）配对时，具有 AIO 电极的全电池表现出高容量和良好的稳定性。“一体式”架构设计的策略为解决先进锌基电池中的锌负极问题提供了启示。
