Abstract
Methods and apparatus for fabricating separators for solid-state lithium metal batteries employ rapid thermal processing. Aspects include high temperature sintering. Temperatures, durations of heat application, and proximity of heating elements to materials undergoing sintering combine to provide separators with desirable physical characteristics, including porosity, in a batch process.
Claims21
1-36. (canceled)
A process for sintering, the process comprising:
- heating a bilayer comprising a green body layer disposed on a metal layer in a furnace at about 1050° C. to about 1250° C. for about 2 minutes to about 10 minutes;
- thereby providing a sintered bilayer comprising a lithium-stuffed garnet layer on the metal layer;
- wherein the bilayer has a thickness, after sintering, of between about 10 μm and about 50 μm.
