Abstract:
1. A process for constructing a rechargeable oxide-ion battery cell comprising the steps: a) forming a membrane assembly of a top air electrode, a bottom negative metal electrode and a middle contacting ceramic electrolyte which extends beyond either the top air electrode, the bottom air electrode or both the top and bottom air electrodes; b) sealing extending sides of the middle contacting ceramic electrolyte to a surface of a metallic frame which surrounds the membrane assembly to form a framed membrane assembly; c) incorporating active material into hollow portions of a metal housing structure to form an active housing structure; d) forming electrically conductive contact between the framed membrane assembly and the active housing structure; and e) joining the framed membrane assembly and the active housing structure to form a rechargeable oxide-ion battery cell.
