Abstract
A reaction vessel in the form of a box is sized to closely contain electrode elements or core cell elements of a lithium-based or sodium-based battery or capacitor for contacting of the electrode material, placed in the reaction vessel, with a flowing gaseous stream of an inert carrier gas and vapor of an organic solvent of water for removing residual water from the porous electrode material elements which are to be infiltrated with a non-aqueous electrolyte solution. Complementary equipment is provided for delivering the gaseous stream to the reaction vessel with predetermined portions of carrier gas and organic vapor at a predetermined temperature, pressure, and flow rate.
