Abstract
Description
Technical Field
[0001] This utility model relates to the field of LIFSI preparation product separation and collection technology, specifically a LIFSI preparation product separation and collection device. Background Technology
[0002] Lithium bis(fluorosulfonyl)imide (LiFSI) is an excellent high-density battery electrolyte additive. LiFSI possesses good electrochemical and thermal stability, improves ionic conductivity and battery charge-discharge characteristics, helps slow battery degradation, and increases the number of battery cycle times. The process involves a metathesis exchange reaction between the organolithium salt in an organic solvent and the bis(fluorosulfonyl)imide metal salt, producing an insoluble organometallic salt precipitate. This precipitate is then separated by filtration, drying, extraction, and further drying to obtain high-purity lithium bis(fluorosulfonyl)imide.
[0003] In existing technologies, when separating and collecting lithium bis(fluorosulfonyl)imide salts, filters or filter plates are often used for filtration. However, when filtering lithium bis(fluorosulfonyl)imide salt precipitates using filters or filter plates, the precipitates that accumulate together require a long filtration time, resulting in a low separation and collection rate for lithium bis(fluorosulfonyl)imide salts.
