Preparation of Anion Exchange Membrane based on Poly(phenylene Oxide) for Vanadium Redox Flow Battery |
| 초록 |
A polyphenylene oxide (PPO)-based anion exchange membrane based on the functionalization of bromomethylated PPO using 1-methylimdazole was fabricated for vanadium redox flow application. The imidazolium-bromomethylated PPO (Im-bPPO) showed lower permeability of VO2+ ions (2.9×10-14 m2/sec), compared to Nafion 212 (2.3×10-12 m2/sec) and FAP-450 (7.9×10-14 m2/sec). Even though the Im-bPPO membrane has higher permeability, the energy efficiency of the VRFB with the Im-bPPO membrane was slightly lower than that of Nafion and FAP-450. The Im-bPPO membrane exhibits good voltage efficiency compared to FAP-450 and Nafion 212 because of its better ion conductivity. The Im-bPPO membrane showed up good performance, but a decline in performance at later cycles was observed. |
