Abstract
An air lithium battery (10) is provided having two equal halves (11) that are joined together along a centerline (12). Each half includes a substrate (13), a carbon based cathode (14), a solid electrolyte (15), an anode (16), an anode current collector (17), and end seals (19). The solid electrolyte includes alternating layers of ion conductive glass (21) and ion conductive polymer (22) materials.

A lithium oxygen battery comprising:
- a first cathode;
- an anode;
- and
- a first solid electrolyte disposed between said first cathode and said anode, said first solid electrolyte having at least one ion conductive glass layer and at least one ion conductive polymer layer.
A lithium oxygen battery comprising:
- a first cathode;
- an anode;
- and
- a first solid electrolyte disposed between said first cathode and said anode, said first solid electrolyte having alternating layers of ion conductive glass and ion conductive polymer.
A solid electrolyte for use in a battery comprising a plurality of ion conductive polymer layers and a plurality of ion conductive glass layers alternating between adjacent pairs of ion conductive polymer layers.
A method of producing a lithium oxygen battery comprising the steps of:
- providing an electrically conductive fiber matrix;
- coating the fiber matrix with a polymer;
- depositing a cathode layer upon the fiber matrix opposite the polymer coating;
- depositing alternating layers of ion conductive glass and ion conductive polymer upon the polymer coating of the matrix to form a solid electrolyte;
- depositing an anode upon the solid electrolyte;
- and
- mounting an anode terminal in electrical contact with the anode.
