Abstract

A simple and effective solvent treatment method was developed to prepare porous membranes with a tunable morphology for vanadium flow battery applications. The solvent treatment method can effectively create poly(ether sulfone) (PES) membranes with a well-controllable pore size and pore size distribution. An impressive vanadium flow battery (VFB) performance with a coulombic efficiency of over 99% and an energy efficiency of over 90% was obtained, which are the highest values ever reported for porous uncharged membranes. The concept provides an entirely novel, simple and cost-effective way to fabricate high-performance porous membranes for VFB applications.

用于钒液流电池应用的高性能多孔不带电膜，通过调整凝聚力和膨胀力†

提出了一种简单有效的溶剂处理方法，用于制备钒液流电池用多孔膜。溶剂处理方法可以有效制备孔径和孔径分布可控的聚醚砜(PES)膜。获得了令人印象深刻的钒液流电池(VFB)性能，库仑效率超过99%，能量效率超过90%，这是迄今为止报道的多孔不带电膜的最高值。该概念为VFB应用提供了一种全新、简单且经济高效的制造高性能多孔膜的方法。
