Abstract:
1. Flexible and hermetically sealed lithium metal anode packaging for large lithium-seawater and lithium-air single semi-fuel cells, which packaging comprises: At least one flexible compliant base layer of a metal foil coated with an electrically insulating heat sealable plastic; a flat lithium metal anode, smaller than and in contact with said flexible base layer, in overlaying relation; at least one metal foil terminal electrically connected to said lithium anode, and extending out of said base layer, and heat sealed to said base layer, at least one porous and flexible inert membrane covering and in contact with said lithium anode, and which membrane is saturated with a lithium ion conductive non-aqueous electrolyte, stable against lithium; a plurality of glass-ceramic water-impermeable lithium ion conductive membranes in contact with said porous flexible inert membrane and with said electrolyte, within footprint of said anode; at least one flexible compliant top layer of a metal foil coated with a heat sealable an electrically insulating plastic, said top layer having openings of matching quantity and positions of said glass-ceramic membranes, and in contact with said glass-ceramic membranes, and hermetically heat sealed to said glass-ceramic membranes, and under vacuum during said sealing to said flexible base layer and to said metal foil terminal, in overlaying relation.
