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.
Claims16
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.
