Abstract
A method is provided for making a ceramic lithium ion conducting membrane and for making an anode pouch for a lithium-seawater battery. The method for making the ceramic membrane includes adding pore formers into a liquid slurry of LTAP (LiO—AlO—SiO—PO—TiO) powder. The liquid slurry is converted into porous green tape and the porous green tape is laminated onto the top of nonporous green tapes to form a stack. The stack is sintered and the pore formers are decomposed to create pores in the top layer of the ceramic membrane. The porous ceramic membrane is used to create a more robust hermetic seal in an anode pouch for the battery compared to a seal made with a nonporous ceramic membrane.
