Verfahren zur Herstellung von cyclischen Perfluoralkanbis(sulfonyl)imiden sowie deren Salze

摘要

The invention relates to a process for the preparation of cyclic perfluoroalkanebis(sulfonyl)imides and salts thereof. The new compound lithium cyclodifluoromethanebis(sulfonyl)imide is outstandingly suitable as a conductive salt in non-aqueous electrolytes for lithium secondary batteries.
