摘要

用于 VRFB 的磺化聚（醚醚酮）（SPEEK）离子交换膜是很有前途的 Nafion 替代品，但需要提高机械和化学稳定性才能长期使用。在这里，我们使用 SPEEK 作为质子传导介质，TiO2 纳米纸作为增强骨架，制作了复合膜，以提高 SPEEK 膜的机械和化学稳定性。与原始 SPEEK（DS=60%）相比，SPEEK/TiO2 纳米纸复合膜的拉伸强度几乎是原始 SPEEK 的两倍，而钒离子渗透率仅为原始 SPEEK 的三分之一。由于这些高耐久性复合膜具有优异的电池性能，如高 EE、容量衰减慢和长期使用寿命长，因此有可能用作商用 VRFB 的离子交换膜。

High durable SPEEK/TiO2 nanopaper composite membrane for vanadium redox flow battery

Sulfonated poly (ether ether ketone) (SPEEK) ion exchange membranes for VRFB are promising alternatives to Nafion, but require improved mechanical and chemical stability for long-term operation. Here, we have fabricated composite membranes using SPEEK as proton conductive medium and TiO₂ nanopapers as reinforcing framework to improve the mechanical and chemical stabilities of SPEEK membranes. The SPEEK/TiO₂ nanopaper composite membranes exhibited almost twice the tensile strength and only one-third the vanadium ion permeability compared to pristine SPEEK (DS=60 %). Due to the excellent cell performance such as high EE, slow capacity degradation and long-term lifetime, these high durable composite membranes could be found their potential use as ion exchange membranes for commercial VRFBs.
