| 20120225959 | PROTON-CONDUCTIVE MEMBRANE - An anhydrous, proton-conductive medium comprises a poly(amic acid)-based polyimide and at least one phosphorus compound from the group consisting of phosphorus oxides and phosphoric acids. The precursor solution for the polyimide is a mixture of a phosphorus oxide and a poly(amic acid). A suitable phosphorus oxide has the formula P | 09-06-2012 |
| 20120214075 | ELECTROCHEMICAL CELL HAVING AIR CATHODE PARTIALLY INFUSED WITH CARBON DIOXIDE - An electrochemical cell has a cell assembly that has an anode, an air cathode infused with a liquid electrolyte, an ionically-conductive separator medium disposed between and coupling said anode and said air cathode, a housing enclosing said anode, said cathode, and said ionically-conductive separator medium, and a mixture of oxygen and carbon dioxide disposed within said housing in gaseous communication with said air cathode, wherein said carbon dioxide comprises from about 0.04% to about 95% molar fraction of said mixture of oxygen and carbon dioxide. | 08-23-2012 |
| 20110223487 | ELECTROCHEMICAL CELL WITH SINTERED CATHODE AND BOTH SOLID AND LIQUID ELECTROLYTE - An electrochemical cell has an anode of electrochemically-active material; a cathode of electrochemically-active, porous, liquid-permeable, sintered, ceramic material; and a solid-state, liquid-impermeable electrolyte medium disposed between the anode and the cathode. The electrolyte may be a layer of glass or a layer of glass ceramic, or may be a combination of a layer of glass and a layer of glass ceramic. The cell may further contain a liquid electrolyte diffused throughout the cathode. | 09-15-2011 |
| 20110053001 | IONICALLY-CONDUCTIVE AMORPHOUS LITHIUM LANTHANUM ZIRCONIUM OXIDE - Amorphous lithium lanthanum zirconium oxide (LLZO) is formed as an ionically-conductive electrolyte medium. The LLZO comprises by percentage of total number of atoms from about 0.1% to about 50% lithium, from about 0.1% to about 25% lanthanum, from about 0.1% to about 25% zirconium, from about 30% to about 70% oxygen and from 0.0% to about 25% carbon. At least one layer of amorphous LLZO may be formed through a sol-gel process wherein quantities of lanthanum methoxyethoxide, lithium butoxide and zirconium butoxide are dissolved in an alcohol-based solvent to form a mixture which is dispensed into a substantially planar configuration, transitioned through a gel phase, dried and cured to a substantially dry phase. | 03-03-2011 |
| 20100273066 | Rechargeable Lithium Air Battery Cell Having Electrolyte with Alkylene Additive - A rechargeable lithium-air battery ( | 10-28-2010 |
| 20100266901 | Lithium Oxygen Battery Having Enhanced Anode Environment - An anode environment mitigates undesired effects of oxygen upon the anode of a lithium-oxygen electrochemical cell. As a means of mitigating oxygen effect, a lithium anode and an air cathode are separated from one another by a lithium-ion-conductive electrolyte separator including material having low oxygen permeability that reduces the amount of oxygen that contacts the anode. As another means of mitigating oxygen effect, a cell comprises lithium-affinity anode material capable of receiving and retaining lithium in a state that is not significantly adversely affected by the presence of oxygen during cell charging and recharging and an air cathode separated by a lithium-ion-conductive electrolyte separator. Lithium-affinity material is capable of drawing lithium thereinto during charging of the cell and retaining the lithium substantially until discharge of the cell. A cell having a lithium-affinity anode may also have a lithium-ion-conductive electrolyte separator including material having low oxygen permeability. | 10-21-2010 |
