Cellfion is developing the next generation of bio-based membranes

Cellfion is a Swedish energytech company paving the way towards a sustainable energy transition through the commercialization of bio-based membranes. Their
technology is made from the most abundant biopolymer on the planet, cellulose, derived from wood. By extracting cellulose nanofibrils from wood, and modifying the surfaces, the fibrils can be fabricated into sheets of membranes that can be used as critical components in energy storage and conversion devices, such as Redox Flow Batteries and fuel cells.

Cellfion stems from 10 years of leading research at KTH Royal Institute of Technology, Linköping University and RISE in Sweden.  The research combined cellulose fiber knowledge with electrochemistry and as a result, Cellfion was born as a company in August 2021.
