Abstract

L'invention porte sur des procédés d'obtention d'éléments électrochimiques non aqueux à l'aide de techniques d'extraction de solvants permettant d'extraire un solvant support d'une anode, d'une cathode, et/ou d'un mélange formant une matrice solide de polymères. Les électrodes et/ou les éléments électrochimiques ainsi obtenus présentent des propriétés améliorées.
