Abstract

New-generation iron–titanium flow battery (ITFB) is attracting wide attention due to its low cost and excellent stability. However, there are few research on the membranes special for iron–titanium flow battery. Herein, we design and fabricate a UiO-66/SPEEK composite membrane suitable for the mild environment of ITFB and exhibiting excellent performance. The introduction of a metal–organic framework (UiO-66) creates abundant nano-scale pores and rich hydrogen bond networks, accelerating the rapid transmission of protons. Furthermore, the proton transport mechanism was analyzed in detail. At the same time, the steric effect of UiO-66 greatly inhibited the swelling and enhanced the stability of the SPEEK membrane. Therefore, the ITFB with UiO-66/SPEEK composite membrane shows higher voltage efficiency (82.9 %) at 40 mA cm⁻² compared with the SPEEK membrane (80.2 %) and runs stably for over 500 cycles at 80 mA cm⁻².

UiO-66构建的丰富氢键使质子在液流电池膜内快速传输

新一代铁钛液流电池因其低廉的成本和优异的稳定性而受到广泛关注。然而，铁钛液流电池专用膜的研究却很少。在此，我们设计并制造了一种适合于ITFB温和环境的UiO-66/SPEEK复合膜，并表现出优异的性能。金属有机框架（UiO-66）的引入创造了丰富的纳米级孔隙和丰富的氢键网络，加速了质子的快速传输。并对质子输运机理进行了详细分析。同时，UiO-66的位阻效应极大地抑制了SPEEK膜的溶胀，增强了SPEEK膜的稳定性。因此，与SPEEK膜（80.2%）相比，UiO-66/SPEEK复合膜的ITFB在40 mA cm - 2下具有更高的电压效率（82.9%），并且在80 mA cm - 2下稳定运行超过500次。
