NOVELTY - Process for purification of a graphite material comprising metal sulfide impurities, involves (a) subjecting the graphite material to oxidizing conditions, in the presence of oxygen, to convert the metal sulfide impurities into metal oxides and sulfur dioxide, and obtaining a metal sulfide-lean graphite material, (b) subjecting the metal sulfide-lean graphite material to carbochlorination, in the presence of chlorine gas, to convert the metal oxides into metal chlorides and obtaining a metal chloride-rich graphite material, and (c) purging the metal chlorides from the metal chloride-rich graphite material, and obtaining a purified graphite material. USE - The process is used for the purification of a graphite material comprising metal sulfide impurities and for purification of a graphite material in lithium-ion batteries. ADVANTAGE - The process allows for high-purity graphite.
