Aqueous zinc-ion batteries (AZIBs) are considered promising candidates for large-scale energy storage due to their high safety, low cost, and environmental friendliness. As a core component, separator plays a unique yet oftentimes overlooked role in providing electrochemical stability in AZIBs. This concept focuses on the exquisite structure-property relationship of separators, highlighting three forms of these components and their structural design requirements, i. e., traditional membranes, solid-state electrolytes, and electrode coatings. The mechanism by which separators influence the zinc anode and the cathode is discussed. The article also identifies the challenges and potential future directions for functional separators in the development of high-performance AZIBs.
水系锌离子电池（AZIBs）因其高安全性、低成本和环境友好性而被认为是大规模储能的有前途的候选者。作为核心组件，隔膜在水系锌离子电池中提供电化学稳定性方面发挥着独特但常常被忽视的作用。本概念聚焦于隔膜的精细结构-性能关系，强调了这些组件的三种形式及其结构设计要求，即传统隔膜、固态电解质和电极涂层。讨论了隔膜影响锌负极和正极的机制。本文还指出了高性能水系锌离子电池开发中功能性隔膜面临的挑战和潜在的未来发展方向。
