dc.description.abstract | Ether-free polyp-phenylene)-based anion exchange membrane materials with outstanding vanadium ion blocking properties are reported. The synthesized ionomers with a rigid backbone structure show small dimensional variations despite the high ion exchange capacities. Among the synthesized membranes, the QPPP-2 membrane with ion exchange capacity of 2.1 meq.g(-1) exhibits high anion (OH-, SO42-, and Cl-) conductivity. The QPPP-2 membrane shows an extremely low diffusion coefficient (2.12 x 10(-9) Cm-2 min(-1)) for VO2+, which is much lower than that of Nafion 115 (2.88 x 10(-6) cm(2) min(-1)), indicating the vanadium ion blocking property of QPPP-2. Moreover, the chemical and operational stabilities of the membranes are investigated via ex situ soaking tests in 0.1 M VO2+ solution and in situ operation tests for 100 cycles, respectively. The vanadium redox flow battery single cell assembled with the QPPP-2 membrane exhibits a coulombic efficiency of 99%, voltage efficiency of 87%, and energy efficiency of 86% during 100 cycles at 80 mA cm(-2). The excellent chemical, morphological, and electrochemical properties of the QPPP-2 membrane make it suitable for use in vanadium redox flow battery. | - |
