Hermetic seal in anode pouch for lithium-seawater electrochemical battery
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 (Li.sub.2OAl.sub.2O.sub.3SiO.sub.2P.sub.2O.sub.5TiO.sub.2) 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.
