Abstract

Composition pour la fabrication d’électrode, électrode et procédé associé L’invention concerne une composition (1) pour la fabrication d’électrode (2), la composition comprenant un composé électriquement conducteur à base de carbone, au moins une espèce propre à former un catalyseur, des microfibrilles de cellulose encapsulant du chitosane. Les microfibrilles de cellulose créent un maillage fibreux liant la composition tout en limitant l’enrobage du catalyseur. Ainsi, le catalyseur reste accessible au milieu environnant, pour permettre les réactions d’oxydoréduction au niveau de l’électrode. Les performances électrochimiques de l’électrode sont par conséquent améliorées. La composition (1) est en outre particulièrement adaptée pour la mise en forme (40) d’électrode par impression 3D.
