METHOD FOR PREPARING HYDROGEN BIS(FLUOROSULFONYL)IMIDE AND METHOD FOR PREPARING LITHIUM BIS(FLUOROSULFONYL)IMIDE

摘要

A method for preparing hydrogen bis(fluorosulfonyl)imide including contacting sulfonyl fluoride with hexamethyl disilazane in an organic solvent. The disclosure also provides a method for preparing lithium bis(fluorosulfonyl)imide (LiFSI). The method includes contacting sulfonyl fluoride with hexamethyl disilazane in an organic solvent and yielding hydrogen bis(fluorosulfonyl)imide; and contacting hydrogen bis(fluorosulfonyl)imide with a lithium compound and yielding lithium bis(fluorosulfonyl)imide.
