Novel Ion Exchange Membrane for High Performance Vanadium Flow battery

本课题旨在设计和合成一种新型的钒氧化还原液流电池(VRFB)离子交换膜，该膜具有离子选择性和高质子导电性。VRFB具有容量与功率解耦、寿命长等优点，是一种很有前途的大规模可再生能源储存技术。目前，由于商用膜具有严重的钒离子渗透性，VRFB存在容量快速衰减和循环不稳定的问题。该项目的预期研究成果包括由高性价比的芳香聚合物制成的稳定、高离子选择性的膜和坚固的纳米膜，从而实现高性能的VRFB。这将使澳大利亚走在清洁能源储存技术的前沿。

This project aims to design and synthesis novel ion exchange membrane with tailored ion selectivity and high proton conductivity for vanadium redox flow battery (VRFB). VRFB is a promising energy storage technology for large scale storing renewable energy due to its advantage of decoupled capacity and power, long lifetime. Currently, VRFB suffers from fast capacity decay and cyclic instability because of severe vanadium ion permeability of commercial membrane. The expected research outcomes in this project include stable, high ion selectivity membranes made of cost-effective aromatic polymer and robust nanofillers, enabling high performance VRFB. This will place Australia in the forefront of clean energy storage technologies.
