  • METHOD FOR PRODUCING BIS(FLUOROSULFONYL)IMIDE LITHIUM SALT (LIFSI) WITH REDUCED FLUORINE ANION CONTENT BY USING ALKOXY TRIALKYL SILANE
    Publication number: 20210347639
    Abstract: A method for producing a bis(fluorosulfonyl)imide lithium salt is disclosed. The method includes the steps of: (a) reacting bis(chlorosulfonyl)imide with NH4F(HF)n (n=0-10) to prepare ammonium bis(fluorosulfonyl)imide; and (b) reacting the ammonium bis(fluorosulfonyl)imide with a lithium base, wherein in at least one of steps (a) and (b), after the reaction, a process of adding an alkoxy trialkyl silane to the reaction solution to remove a fluorine anion is performed.
