  • Publication number: 20260097396
    Abstract: A process for producing a coated membrane for an anionic exchange membrane electrode assembly includes mixing a PGM-free catalyst, an ionomer, and an anhydrous solvent forming a solution, coating a non-fluorinated substrate with the solution forming a coated substrate and drying the coated substrate allowing the anhydrous solvent to evaporate forming a dried coated substrate. The dried coated non-fluorinated substrate is applied to a surface of a hydroxyl-free anion-exchange membrane including non-hydroxyl ions forming a membrane substrate assembly that is pressed using a hot-press. The substrate is removed from the pressed membrane substrate assembly forming a coated membrane. The non-hydroxyl ions in the anionic exchange membrane are replaced by hydroxyl ions by soaking the coated membrane in a hydroxyl ion solution.

  • Patent number: 10439204
    Abstract: A method for producing an electrode active coating on a current collector comprising providing isolated lignin and subjecting the isolated lignin to a pre-treatment in order to remove low molecular mass fractions of the lignin. The pre-treated lignin is mixed with an electrode active material, water and a conductive additive material so as obtain a slurry adapted for coating of a current collector. The coating obtained by the method comprises pre-treated lignin as a binder. The coating obtained has good binding properties between the particles of the coating as well as to the current collector. Furthermore, it has excellent electrochemical properties during use in a lithium-ion battery.
