Synthesis and investigation of ether-free polymeric anion exchange materials with outstanding efficiency and low vanadium permeability for vanadium redox flow battery (VRFB) application |
| 초록 |
Anion exchange membranes (AEMs) are considered some of the most promising electrolytes for use in the vanadium redox flow battery (VRFB). To realize high-performance for VRFBs, AEMs that exhibit excellent stability and long-term durability are required. Herein, a series of ether-free poly(p-phenylene)s containing a quaternary ammonium group or imidazolium group were synthesized via Ni(0)-catalyzed coupling polymerization, benzylic bromination, and in situ amination, successively. The synthesized ionomers consisting of poly(p-phenylene) with different functional groups were investigated for chemical and dimensional stability and for VRFB performance. The water content and swelling behavior of the developed AEMs remained stable at room temperature. Furthermore, the small-angle X-ray scattering profiles indicated phase-separated morphological characteristics of the synthesized AEMs, even with a random copolymer. |
