CONSTRUCTION OF PLANAR RECHARGEABLE OXIDE-ION BATTERY CELLS AND STACKS USING STAINLESS STEEL HOUSING STRUCTURES

摘要

This present invention describes the 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. This invention also describes the processing steps for assembling a ROB stack using the constructed cells including: f) installing cell-to-cell current collector (58) between the air electrode (20') of a first ROB cell (80), and the central section of the bottom surface (70) of the metal housing structure (30') of a second successive ROB cell (82); and g) forming insulation seal (72) between the top surface (74) of the picture frame of the first ROB cell and the bottom peripheral section (76) of the metal housing structure of the second successive ROB cell
