Microporous Membranes Team
Winner: 2023 Materials Chemistry Horizon Prize: Stephanie L Kwolek Prize
For the development of ion-conducting polymers of intrinsic microporosity and applications as next-generation membranes in redox flow batteries for grid-scale energy storage.
Celebrate Microporous Membranes Team
A team of chemists and engineers from Imperial College London and the University of Edinburgh have collaborated on the development of a new generation of ion-conducting membranes based on polymers of intrinsic microporosity and demonstrated their exceptional performance in organic-based redox flow batteries (RFB) chemistries.
RFBs are a promising grid-scale energy storage technology for the integration of electricity generated from intermittent renewables into the power grid. Membranes are a crucial component in flow batteries, allowing the conduction of charge-carrier ions but minimizing the crossover of redox-active species, and they contribute up to 40% of the RFB capital cost. Commercial Nafion membranes are widely used, but they are expensive, poorly selective towards redox-active molecules and are produced by environmentally damaging processes that involve the use of poly-fluoroalkyl substances, known as forever chemicals.

These microporous membranes can be used for a variety of applications, including in the storage of renewable energy, and so they have the potential to make a real positive impact in the fight against climate change.
