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.
