Researchers at Imperial College London, supported by colleagues at a range of other institutions, have published a study in Nature that will help fine-tune a new class of ion exchange membranes. The results should make it possible to build longer lasting and more cost- and energy-efficient devices such as flow batteries, a promising technology for long-duration grid-scale energy storage.
