Flow Battery with Remarkably Stable Performance at High Current Density: Development of A Nonfluorinated Separator with Concurrent Rejection and Conductivity

Angewandte Chemie, Volume 137, Issue 25, June 17, 2025.
Organic redox flow batteries are promising for grid stabilisation, but the insufficient ion separation by membrane separator can limit the lifetime and increase the cost. Here, we present an ultra‐ion‐selective SPEEK‐SX membrane, it enables 600 cycles at 160 mA cm−2 with only 0.00935% per cycle capacity decay, outperforming Nafion‐212, offering a ...
