Gas permeable flexible graphite sheet material and process therefor

摘要

A process for preparing a gas permeable flexible graphite sheet is presented. The process includes providing graphite flakes; admixing the graphite flakes with a sacrificial additive to form a graphite mixture; compressing the graphite mixture into a sheet having sacrificial additive dispersed therethrough; and treating the sheet to at least partially remove the sacrificial additive to form a permeable flexible graphite sheet.
