Abstract

This invention describes a capacitor that formed by a charge or species specific membrane material filled with aqueous or non-aqueous liquid with soluble salts dissolved and non-dissolved in solution and contained within the membrane material. When charged, the oppositely charged ion will leave the structure, leaving behind a charged atomic capacitor.

    DETAILED DESCRIPTION OF THE INVENTION
  • In an electric double layer capacitor system such as but not limited to the concentric capacitive deionization Radial Deionization device from Atlantis Technologies, two oppositely charged capacitors are separated by a dielectric flow channel and two charge specific membranes. In the purification mode, cations are attracted to the negatively charged carbon electrode and anions are attracted to the positively charged carbon electrode. Each type of ion passes through a membrane whose charge affinity is the same as the ion (positive or negative). After it passes through, it adsorbs onto the surface of the carbon particles that make up the carbon electrode. See FIG. 1.
  • Once the purification cycle is complete or the carbon electrodes are full of their respective ions, the polarity of the electric double layer capacitor is switched and the ions are pushed away from the carbon, through the membrane, into the spacer and up against the opposite side membrane. Because the membranes are charge specific, these rejected ions cannot pass through and adsorb onto the other carbon electrode and flush out of the system. See FIG. 2.
  • This invention proposes the partial or complete replacement of the carbon electrodes and charge specific membrane with charge specific membrane material that contains aqueous or non-aqueous solution that is saturated with high solubility salts such as but not limited to sodium chloride, antimony trichloride, ammonia, antimony trifluoride, zinc chloride, zinc bromide, indium bromide, or any other high solubility salt that dissolved and non-dissolved in aqueous or non-aqueous solution.
  • When the atomic capacitor material is initially made, the cations and anions from the highly soluble salt are in solution and the solution is contained within the charge specific membrane material 11 or 12, as shown in FIG. 3, which shows atomic capacitor spheres filled with salt in aqueous or non-aqueous or solution. The membrane material could be a porous layer of material with a multitude of holes for the aqueous or non-aqueous solution to reside 31, as shown in FIG. 4, which shows charge specific membrane material with voids filled with salt in aqueous or non-aqueous solution. This combination could also be in the form of hollow spheres containing the salt laden liquid 33, as shown in FIG. 5, which shows carbon electrode material containing hollow spheres filled with salt in aqueous or non-aqueous or solution, or FIG. 6, which shows an integrated carbon electrode and charge specific membrane material with voids filled with salt in aqueous or non-aqueous solution. In either case, it is important that the outside of the material be sealed and that there is no significant pathway for the liquid to leave the interior of the membrane sponge or sphere.
  • An electric double layer capacitor is formed with one of the charge specific membrane compositions constituting one electrode, and the opposite polarity membrane composition constituting the other as described in the attached drawing as optional. When an initial activation charge is applied to the device in the same orientation as the charge specific membranes (anionic side is charged negative, cationic side charged positive), the anions travel out of the anionic and move into the dielectric spacer towards the positively charged electrode. The cations leave the cationic and travel towards the anionic side. This polarity orientation is same as the “reject cycle”.
  • By the end of this initial activation charging cycle, most or all of the anions 17 and cations 15 have left the anionic and cationic spheres or pockets respectively and are residing in the dielectric spacer. With the polarity intact, the ejected ions are flushed out of the system by a liquid flowing through the flow channel/dielectric spacer.
  • After this initial charging cycle, each sphere is now charged to the opposite polarity due to the inability of the trapped ions to leave the sphere or pocket and is now ready to operate on a continuous basis. To operate, the polarity is switched to the “clean cycle” and the previously ejected ion type (anionic or cationic) is reabsorbed by the sphere from the solution flowing through the dielectric spacer flow channel.
  • The size, shape, and composition of the atomic capacitors can vary. Capacitor can be a stand-alone structure containing a membrane shell filled with aqueous or non-aqueous liquid containing dissolved and undissolved salts (capacitor mixture), as shown in FIG. 6. It can also be a void within a membrane structure which is also filled with capacitor mixture, as shown in FIG. 4. The shape can range from spherical to any shape that would hold volume. The total volume of the capacitor can be as small as the size of a one salt molecule with minimum liquid up to many milliliters. The wall thickness of a stand-alone structure could be the minimum to contain the liquid such as the length of a membrane molecule, a single layer of graphene or other high strength material.

  • An electrode/membrane combination consisting of a porous charge specific membrane material that is filled with a highly soluble salts such as but not limited to metal halides such as sodium chloride, antimony trichloride, ammonia, antimony trifluoride, zinc chloride, zinc bromide, indium bromide, or any other high solubility salt that dissolved and non-dissolved in aqueous or non-aqueous solution.
    • Example 2
  • Charge specific membrane hollow spheres consisting of charge specific membrane material that is filled with a highly soluble salt such as but not limited to sodium chloride, antimony trichloride, ammonia, antimony trifluoride, zinc chloride, zinc bromide, indium bromide, or any other high solubility salt that dissolved and non-dissolved in aqueous or non-aqueous or solution. These spheres can be incorporated into materials used within an electrochemical device such as capacitive deionization systems.
    • Example 3
  • An electrode/membrane combination consisting of a porous charge specific membrane material that is filled with a highly soluble salt such as but not limited to sodium chloride, antimony trichloride, ammonia, antimony trifluoride, zinc chloride, zinc bromide, indium bromide, or any other high solubility salt that dissolved and non-dissolved in aqueous or non-aqueous solution in combination with traditional capacitance materials such as but not limited to carbon black, activated carbon, and PTFE fibrillating materials.

These spheres can be adhered in some fashion to the current collector with conductive adhesive and act as both the capacitor material and charge specific membrane.
