Cellfion is a start-up company founded in 2021 

working with manufacturing and developing nano-cellulose based ion-selective membranes for electrochemical energy and conversion devices. With our head office based in Norrköping, Sweden we work closely with research institutes in Norrköping, Stockholm and our customers to ensure the continuous development of our membranes.  


The transition from fossil fuels to renewable energy is happening at an unprecedented rate as the need to reduce greenhouse gases from our atmosphere to limit the effect of global warming rises. Due to the increase in energy production from renewable sources such as wind and solar, the need for energy storage and conversion devices have never been more in demand.  Our mission is to make sure that this transition can continue to grow at an exponential rate by producing optimisable and sustainable membranes for a range of electrochemical energy applications which will play a critical role in securing a sustainable future. 


We believe that the greenest energy solutions deserve the greenest materials. In order for renewable energy to be completely sustainable then the materials used for energy storage and energy conversion need to be as well. That’s why Cellfion produces bio-based membranes made from the most abundant biomass organic substance on the planet to serve our customers' needs.  


Cellfion's core product is an innovative use of an abundant natural resource. We derive nano-cellulose from wood and then fabricate them to make ion-selective semi-permeable membranes. Through the know-how of our exceptional scientific team, Cellfion brought together electrochemical competencies from Linköping University (LiU) and RISE with nanocellulose experts from KTH to create a sustainable and unique membrane.     

Our Ambition 

Our ambition is to deliver optimized membranes to our customers to enable the next level of electrochemical devices. Begining with targeting two niche markets we are currently tuning cation-exchange membranes for PEM electrolysers and Redox Flow Batteries, with the goal of scaling production in 2023.
