Hermetic seal in anode pouch for lithium-seawater electrochemical battery

A method of making an anode pouch for a lithium-seawater battery comprising:

• providing a water impermeable ceramic lithium ion conducting membrane having a porous top layer, wherein the porous top layer has a plurality of substantially spherical shaped pores formed therein that intersect a top surface of the porous top layer to form pore openings;
• and
• adhering the porous top layer of said ceramic lithium ion conducting membrane to an annular laminate face ring to provide a hermetic seal between the ceramic lithium ion conducting membrane and the annular laminate face ring;
• wherein the annular laminate face ring comprises an aluminum layer, an adhesive layer on a first side of the aluminum layer, and an abrasion-resistant waterproof material layer on a second, opposite side of the aluminum layer;
• wherein said step of adhering comprises:
• melting the annular laminate face ring adhesive layer;
• positioning the water impermeable ceramic lithium ion conducting membrane porous top layer against the melted adhesive layer whereby the melted adhesive enters the porous top layer pore openings;
• and
• cooling the positioned water impermeable ceramic lithium ion conducting membrane and annular laminate face ring.
