PROCESS FOR PURIFYING A LITHIUM BIS(FLUOROSULFONYL)IMIDE SALT

摘要

The invention relates to a process for purifying a lithium bis(fluorosulfonyl)imide salt. The present invention relates to a process for purifying a lithium bis(fluorosulfonyl)imide salt in a solution in at least one solvent S1, said process comprising at least one purification step carried out in: - a piece of silicon carbide-based or fluorinated polymer-based equipment; or - a piece of metal or glass equipment comprising an inner surface, said inner surface, which can come into contact with the lithium bis(fluorosulfonyl)imide salt, being covered with a polymer coating or with a silicon carbide coating.
