The toxic solvent has been removed and the fluorinated binder has been replaced by cellulose fibers and microfibrils.

Using a simple filtration in aqueous medium procedure, the fibers are destructured at the nanometric scale, thus forming a 3D network which provides both mechanical resistance and good contact between the conducting particles. The demonstrator is in the maturation process, supported by GRAVIT – – and the researchers are seeking industrial partners for further development and commercialization.
