Abstract: An ion exchange membrane includes a matrix including a fluorinated polymer and a filler including cellulose nanocrystals. A method of making the ion exchange battery includes coating a solution including the fluorinated polymer and the cellulose nanocrystals onto a substrate, removing solvent from the coated substrate to provide the membrane, and removing the membrane from the substrate. The ion exchange membrane can be useful for a variety of applications including fuel cells, sensors, electrolytic cells, redox flow batteries, gas separators, humidifiers, and metal ion batteries.
