  • Publication number: 20170110714
    Abstract: A method for electrochemical deposition of refined lithium metal to form a lithium anode in situ in a lithium (Li) ion battery comprising providing a fully lithiated cathode, providing a metal anode, providing a block copolymer electrolyte membrane between the cathode and the metal anode, and polarizing the cathode and the metal anode in the lithium ion battery to cause Li ions to migrate from the cathode through the block copolymer electrolyte and cause the electrochemical deposition to deposit refined lithium metal on the metal anode to form the lithium anode.

  • Patent number: 9525190
    Abstract: Various embodiments of the invention disclose that the uptake of LiOiPr in Mg2(dobdc) (dobdc4?=1,4-dioxido-2,5-benzenedicarboxylate) followed by soaking in a typical electrolyte solution leads to a new solid lithium electrolyte Mg2(dobdc).0.35LiOiPr.0.25LiBF4.EC.DEC. Two-point ac impedance data show a pressed pellet of this material to have a conductivity of 3.1×10?4 S/cm at 300 K. In addition, the results from variable-temperature measurements reveal an activation energy of approximately 0.15 eV, while single-particle data suggest that intraparticle transport dominates conduction.

  • Patent number: 9346921
    Abstract: The present disclosure relates to high molecular weight polystyrene-polydialkylsiloxane-polystyrene (“SDS”) triblock copolymer compositions and methods of separating one or more organic compounds from an aqueous solution using membranes derived from SDS triblock copolymers. The methods may be used to separate the one or more organic compounds from an aqueous solution produced in a fermentation process. In some embodiments, the one or more organic compounds include an alcohol, such as, for example, ethanol. In other embodiments, the one or more organic compounds include acetone. In other embodiments, the one or more organic compounds include acetone, ethanol, and n-butanol produced in an acetone-ethanol-n-butanol (ABE) fermentation process. In other embodiments, the one or more organic compounds include one or more byproducts produced in a fermentation process.

  • Patent number: 8440765
    Abstract: The present invention relates to copolymer compositions for alcohol-selective membranes and methods of selectively separating an alcohol such as ethanol from an aqueous solution using such membranes. The copolymer compositions may be block copolymers of polystyrene-polybutadiene-polystyrene (hereafter “SBS”) having cylindrical morphologies; graft diblock copolymers synthesized by ring-opening metathesis polymerization of two cycloalkene monomers, wherein at least one of the cycloalkene monomers is substituted with one or more polydialkylsiloxane groups; or triblock copolymers comprising a middle block comprising a polymerized cycloalkene monomer and two end groups. The synthesized graft and triblock copolymer compositions may have a spherical, lamellar, cylindrical, double diamond, or gyroid morphologies. The copolymer compositions may contain a structural block that imparts essential mechanical properties to the membrane (e.g., polystyrene) and may also contain an alcohol transporting block (e.g.
