Abstract
A method for removing plasticizers such 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.
