The current graphite purification process. Today, nearly of the purification of natural flake graphite-based anode materials and more than 60% of the production of synthetic graphite used in Li-ion battery (LiB) cells, is performed in China. This is done either by acid/caustic leaching or by thermal processing in Acheson furnaces.
