Abstract
La présente invention concerne un procédé de séchage et purification d'un sel de lithium de bis(fluorosulfonyl)imide en solution dans un solvant organique S1, ledit procédé comprenant les étapes suivantes : a) addition d'eau désionisée pour dissoudre et extraire le sel lithium de bis(fluorosulfonyl)imide, formant une solution aqueuse dudit sel ; b) extraction du sel de lithium de bis(fluorosulfonyl)imide à partir de ladite solution aqueuse, avec un solvant organique S2, cette étape étant répétée au moins une fois; c) concentration du sel de lithium de bis(fluorosulfonyl)imide par évaporation dudit solvant organique S2 et de l'eau, dans un évaporateur à film mince à court trajet, dans les conditions suivantes : - température comprise entre 30°C et 95°C; - pression comprise entre 10-3 mbar abs et 5 mbar abs ; - temps de séjour inférieur ou égal à 15 min ; d) éventuellement cristallisation du sel de lithium de bis(fluorosulfonyl)imide. La présente invention concerne également un sel de lithium de bis(fluorosulfonyl)imide, et ses utilisations dans les batteries Li-ion.
