Title (EN) METHOD OF PREPARING ELECTROCHEMICAL CELLS
(FR) PROCEDE DE PREPARATION DE PILES ELECTROCHIMIQUES
Abstract:
(EN) A method for activating the anode, cathode, and polymeric matrix components of an electrochemical cell is provided. Subsequent to forming the electrochemical cell precursor a quantity of activation fluid comprising electrolyte solvent and an inorganic salt is added into the electrochemical cell precursor at a rate such that substantially all of the activation fluid is incorporated into the electochemical cell precursor. The method produces electrochemical cells having consistent amounts of solvent and salts therein.
(FR) L'invention porte sur un procédé d'activation de l'anode, de la cathode et des composants de la matrice de polymères d'une pile électrochimique. Après la formation du précurseur de pile électrochimique, on lui ajoute une certaine quantité d'un fluide activateur comprenant un solvant électrolytique et un sel inorganique tel que la totalité du fluide activateur de trouve incorporée dans ledit précurseur. Le susdit procédé permet d'obtenir des piles électrochimiques comportant des quantités stables de solvant et de sels.
