Aqueous aluminum metal batteries (AMBs) have attracted numerous attention because of the abundant reserves, low cost, high theoretical capacity, and high safety. Nevertheless, the poor thermodynamics stability of metallic Al anode in aqueous solution, which is caused by the self-corrosion, surface passivation, or hydrogen evolution reaction, dramatically limits the electrochemical performance and hampers the further development of AMBs. In this comprehensive review, the key scientific challenges of Al anode/electrolyte interface (AEI) are highlighted. A systematic overview is also provided about the recent progress on the rational interface engineering principles toward a relatively stable AEI. Finally, suggestions and perspectives for future research are offered on the optimization of Al anode and aqueous electrolytes to enable a stable and durable AEI, which may pave the way for developing high-performance AMBs.
水系铝金属电池（AMBs）因其储量丰富、成本低廉、理论容量高和安全性高而备受关注。然而，金属铝阳极在水溶液中热力学稳定性较差，这是由自腐蚀、表面钝化或析氢反应引起的，极大地限制了其电化学性能，阻碍了水系铝金属电池的进一步发展。在这篇综述中，突出了铝阳极/电解质界面（AEI）的关键科学挑战。还系统概述了针对相对稳定的AEI的合理界面工程原理的最新进展。最后，就优化铝阳极和水系电解质以实现稳定持久的AEI提供了未来研究的建议和展望，这可能为开发高性能水系铝金属电池铺平道路。
