Title:
METHOD FOR PREPARING LITHIUM FLUOROSULFONYLIMIDE BY USING ORGANIC SOLVENT
Document Type and Number:
WIPO Patent Application WO/2017/126851
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing lithium fluorosulfonylimide and, particularly, provides a method for preparing lithium fluorosulfonylimide from a mixture containing a fluorosulfonylimide inorganic salt, a lithium salt, and a solvent containing an oxygen-containing organic compound. Configured to easily remove water and the solvent and thus to readily crystalize lithium fluorosulfonylimide, the method for preparing lithium fluorosulfonylimide according to an embodiment of the present invention can be used in the economical mass production of lithium fluorosulfonylimide used as an electrolyte of a secondary battery.
