A method for removing plasticizers such as dibutyl phthalate from the anode, cathode, and polymeric matrix components of electrochemical cell precursors using carbon dioxide in the supercritical state is provided. The method forms porous polymeric structures that enhances the mass transport of ions in the cell which results in improved electrochemical performance.
Procédé d'élimination des plastifiants tels que le phthalate de dibutyle des constituants d'anode, de cathode et de matrice polymère de précurseurs de piles électrochimiques à l'aide de dioxyde de carbone à l'état surcritique. Le procédé forme des structure polymère poreuses améliorant le transport massique d'ions dans la pilece qui a pour effet d'améliorer le rendement électrochimique.
