Abstract

A method and apparatus for making lithium/air batteries with LiPON as separator and protective barrier, and the resulting cell(s) and/or battery(s). Some embodiments include an apparatus that includes a lithium anode; a polymer-air cathode; and a LiPON separator between the anode and cathode. In some embodiments, the polymer-air cathode includes a carbon-polyfluoroacrylate material. In some embodiments, the anode overlays a copper anode contact.

Claims

1. An apparatus comprising:

a lithium anode;

a polymer-air cathode; and

a LiPON separator between the anode and cathode.

2. The apparatus of claim 1, wherein the polymer-air cathode includes a carbon-polyfluoroacrylate material.

3. The apparatus of claim 2, wherein the anode overlays a copper anode contact.

4. A method comprising:

depositing a lithium anode on a substrate;

depositing a LiPON separator over the anode; and

depositing a polymer-air cathode on the separator.

5. The method of claim 4, wherein the polymer-air cathode includes a carbon-polyfluoroacrylate material.

6. The method of claim 5, wherein the anode is deposited as a layer on a copper anode contact layer.

7. An apparatus comprising:

a lithium anode on a substrate; and

means for depositing a LiPON separator over the anode and for depositing a polymer-air cathode on the separator.

8. The apparatus of claim 7, wherein the polymer-air cathode includes a carbon-polyfluoroacrylate material.

9. The apparatus of claim 8, wherein the anode contacts a copper anode contact layer.
