Abstract
Processing steps for constructing a rechargeable oxide-ion battery (ROB) cell using a cell membrane assembly 40 and a hollow metal housing structure 30 wherein assembly steps include: a) forming a membrane assembly 40 of air electrode 20, metal electrode 24 and electrolyte 22 therebetween; b) sealing the membrane assembly 40 to a surrounding frame 26; c) filling the hollow metal housing structure 30 with active material 32; d) forming electrical contact between the framed membrane assembly and the filled housing structure; and e) joining the framed membrane assembly and the active housing structure to form a ROB cell.
