摘要

全钒液流电池质子交换膜性能直接决定电池性能。磺化聚醚醚酮(SPEEK)膜凭借结构简单、可调控的磺化度及成本优势，展现出替代Nafion膜的潜力。本文以SPEEK基隔膜为综述对象，围绕“如何平衡质子传导率与阻钒性能”这一核心问题展开，系统梳理了有机−无机复合、交联结构构筑、表面功能化及多孔结构调控等主流改性策略，重点探讨了不同改性方法对膜材料选择性的提升机制。最后对SPEEK基隔膜的开发所面临的挑战以及可能的未来研究方向进行了探讨。

Abstract

The performance of proton exchange membranes in vanadium redox flow batteries directly determines battery efficiency. Sulfonated polyether ether ketone (SPEEK) membranes demonstrate great potential to replace Nafion membranes due to their simple structure

controllable sulfonation degree

and cost advantages. This review focuses on SPEEK-based membranes

centering on the core issue of “how to balance proton conductivity and vanadium ion permeation resistance”. It systematically summarizes mainstream modification strategies including organic-inorganic hybridization

cross-linked structure construction

surface functionalization

and porous structure regulation

with a focus on discussing the enhancement mechanisms of different modification methods on the selectivity of membrane materials. Finally

the challenges faced in the development of SPEEK-based membranes and potential future research directions are discussed.
