Imagine a filter that lets specific particles through to create electricity, but instead of using toxic chemicals, it's made from wood fibers. It works like a high-tech sponge that manages ions without polluting the planet. This replaces harmful 'forever chemicals' with a natural, biodegradable alternative that is much cheaper to make.
Current energy membranes rely on toxic PFAS chemicals, which are facing imminent EU bans and cause billions in health costs. Companies need a sustainable, non-toxic alternative that doesn't sacrifice performance or increase costs.
A PFAS-free, cellulose-based ion-selective membrane and a scalable roll-to-roll manufacturing process with reduced solvent requirements.
If you are a battery manufacturer dealing with the high cost and toxicity of PFSA membranes — this project developed a cellulose-based membrane that is 27 times more cost-effective and PFAS-free.
If you are a producer dealing with upcoming EU bans on PFAS substances — this project developed a bio-based ion-selective membrane that maintains high performance while ensuring regulatory compliance.
If you are a supplier dealing with inefficient solvent-heavy production — this project developed a manufacturing process that reduces solvent use by 48% and uses roll-to-roll processing for scale.
The bio-based, ion-selective membrane is 27 times more cost-effective compared to competing solutions.
Yes, the project optimized pressurized and evaporation-based dewatering methods to support semi-automated roll-to-roll processing.
The project developed various chemical and physical crosslinking strategies, many of which are currently patent pending.
It provides a PFAS-free alternative to toxic PFSA-based membranes, helping companies avoid the health costs of PFAS usage estimated between €52 and €84 billion per year.
Integration with membrane electrode assemblies (MEAs) was achieved through spray-coating and validated at the system level.
The project is led by a single Swedish SME, Cellfion AB, which acted as the sole partner. This lean structure allowed for rapid iteration from material optimization to roll-to-roll manufacturing validation, though it lacks the diverse academic or large-scale industrial partner network typically seen in larger consortia.
