钒电池用离子交换膜的研究与开发

Research and Development of Ion Exchange Membranes for Vanadium Redox Battery

钒电池(VRB)是一种新型的高效储能电池。离子交换膜是VRB的核心部件之一。总结了VRB用离子交换膜在商业化膜(Nafion、PE-01、JAM等)改性处理及PVA、PVDF、PTFE基阳离子交换膜和ETFE、PPESK基阴离子交换膜研发等方面近4年来的技术进展,指出需重点关注高性能、低成本膜的开发,尤其是新型阴离子交换膜的研究与开发。

Ion exchange membrane（IEM）is one of the key components for vanadium redox battery（VRB）, a novel energy storage battery. The progress in modification of the commercially available membranes（Nafion, E-01 and JAM etc. ）, research and development （R ＆ D） of PVA-based, VDF-based and PTFE-based cation exchange membranes and ETFE-based and PPESK-based anion exchange membranes for VRB in the last four years is reviewed. It is pointed out that the R ＆ D of high performance IEM with low cost, especially, the anion exchange membrane, should be paid more attention.
