Problem
Current membrane technologies used in hydrogen, battery, and ion-separation applications often rely on per- and polyfluoroalkyl substances (PFAS), which pose significant environmental and health risks due to their persistence and toxicity. The dependency on these substances hinders the development of sustainable and eco-friendly energy storage and separation solutions.
Solution
Cellfion provides cellulose-based membranes that are completely free of PFAS, offering a sustainable alternative for hydrogen, battery, and ion-separation technologies. These membranes are derived from wood-based biopolymers, the most abundant on the planet, and manufactured through a clean fabrication process. By modifying and treating the cellulose, Cellfion can adapt membrane characteristics such as ion conductivity, swelling ratios, and mechanical integrity to meet specific application requirements. This innovative approach leverages a reliable and low-volatility raw material to produce high-quality membranes and nanoparticle dispersions suitable for various applications in clean energy.
