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.
