Abstract
A battery (10) is disclosed having a lithium foil anode (11) embedded within a liquid electrolyte (12) which is positioned between two similarly constructed battery cathode halves (13) and (14). Each cathode half has a first glass barrier (16) coupled to a first porous metal substrate (17), a second glass barrier (18) coupled to a second porous metal substrate (19), a third glass barrier (20) coupled to a third porous metal substrate (21), and a lithium air cathode (22). A peripheral layer of edge sealant (25) surrounds the peripheral edge of the electrolyte and bonds the two halves together. The battery also includes an anode terminal (27) coupled to the anode and a cathode terminal (28) coupled to the cathode.
Claims6
A method of manufacturing an air battery comprising the steps of:
- (a) providing a viscous air cathode layer;
- (b) placing a first porous support substrate upon the viscous air cathode layer so as to allow a portion of the viscous air cathode layer to be drawn into the first porous support substrate;
- (c) depositing a first glass barrier layer upon the first porous support substrate;
- (d) positioning an anode adjacent the glass barrier layer;
- (e) positioning an electrolyte between the anode and the glass barrier layer, and
- (f) passivating the pores of the first porous support substrate with metal plugs having an electrically insulative top layer.
