| 20090004371 | AMORPHOUS LITHIUM LANTHANUM TITANATE THIN FILMS MANUFACTURING METHOD - An amorphous lithium lanthanum titanate (LLTO) thin film is produced by the sol-gel method wherein a polymer is mixed with a liquid alcohol to form a first solution. A second solution is then prepared by mixing a lanthanum alkoxide with an alcohol. The first solution is then mixed with the lanthanum based second solution. A lithium alkoxide and a titanium alkoxide are then also added to the lanthanum based second solution. This process produces a batch of LLTO precursor solution. The LLTO precursor solution is applied to a substrate to form a precursor layer which is then dried. The coating techniques that may be used include spin coating, spraying, casting, dripping, and the like, however, the spin coating technique is the preferred method recited herein. | 01-01-2009 |
| 20090053594 | RECHARGEABLE AIR BATTERY AND MANUFACTURING METHOD - An air battery having an air cathode having a porous carbon based air cathode containing a non-aqueous organic solvent based electrolyte including a lithium salt and an alkylene carbonage additive.

| 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 |
