摘要：

铁铬氧化还原液流电池（ICRFBs）因其活性物质（铁、铬）储量丰富、电解液成本低且环保的特性，在大规模储能领域表现出广阔应用前景，特别适用于可再生能源大规模接入电网时的功率波动调节。离子传导膜作为ICRFBs的核心组件，在传导载流子和阻止Fe3+/Cr3+等交叉渗透方面发挥关键作用，其性能直接影响电池的效率、循环寿命和成本。本文系统分析了ICRFBs对膜材料的性能要求，总结了商业全氟磺酸膜的筛选与优化研究进展，以及非氟离子传导膜的发展情况；通过比较不同膜材料的电池效率，评估其优点与局限性，并讨论了高性能膜材料未来的研发方向。

Iron-chromium redox flow batteries (ICRFBs) have broad prospects for applications in large-scale energy storage, attributed to the abundant reserves of active materials (iron and chromium), as well as the low-cost and environmentally friendly electrolytes, making them especially suitable for mitigating fluctuations arising from the large-scale integration of renewable energy into power grids. As a core component of ICRFBs, the ion-conducting membranes play a critical role in facilitating the transport of charge carriers while inhibiting the crossover of Fe3+/Cr3+. Their performance directly dictates the batteries’ efficiency, cycle life, and overall cost. Herein, we systematically analyze the performance requirements of membrane materials for ICRFBs, summarize the research progress in the selection and optimization of commercial perfluorosulfonic acid membranes, and review the development of non-fluorinated ion-conducting membranes. By comparing the batteries’ efficiency of diverse membranes in ICRFBs, we further evaluate their respective advantages and limitations, and discuss the research future directions for the development of high-performance membrane materials.
