Abstract: Apparatus for separating CO2 from an electrolyte solution are provided. Example apparatus can include: a vessel defining an interior volume and configured to house an electrolyte solution; an input conduit in fluid communication with the interior volume; an output conduit in fluid communication with the interior volume; an exhaust conduit in fluid communication with the interior volume; and an anode located within the interior volume. Other example apparatus can include: an elongated vessel having two regions; an input conduit extending outwardly from the one region; an output conduit extending outwardly from the other region; an exhaust conduit in fluid communication with the one region; and an anode located within the one region. Methods for separating CO2 from an electrolyte solution are provided. Example methods can include: providing a CO2 rich electrolyte solution to a vessel containing an anode; and distributing hydrogen from the anode to acidify the electrolyte solution.

Abstract: Methods and feedstock compositions for preparing porous electrodes as contained in lithium ion and lithium polymer batteries that comprise an electrolyte composition are described. The methods are characterized by depositing on a substrate a feedstock having a soluble pore former, precipitating at least a portion of the soluble pore former from the feedstock, and dissolving the solid pore former from the electrode using at least a portion or constituent of the electrolyte composition. The feedstock compositions are characterized by a pore former that forms a two-phase system with at least one constituent of the electrolyte composition. The feedstock does not contain materials that are not also substantially contained in the lithium ion battery.
