Definitions

• EP 3203570 (Nippon Shokubai Co., Ltd.) discloses a method producing an electrolyte solution material containing a fluorosulfonylimide salt and a solvent, characterized in decompressing and/or heating a solution containing the fluorosulfonylimide salt and the electrolyte solution solvent to volatilize a fluorosulfonylimide salt production solvent.
• Step c) may be carried out at a temperature of between 0°C and 50°C, for example between 15°C and 35°C, and preferably at about room temperature.
• F- a fluoride (F-) content of below 100 ppm, preferably below 50 ppm, more preferably below 40 ppm, more preferably below 30 ppm, more preferably below 20 ppm;
• the alkali salt of FSI of the present invention is an alkali metal salt, preferably a lithium salt of bis(fluorosulfonyl)imide, Li + (FS02)2N ⁇ (LiFSI).
• the lithium salt of bis(fluorosulfonyl)imide may be characterized by the following impurity profile:
• a tri-necked 250m L glass flask was equipped with a thermometer, a mechanically-stirred 4-blades shaft and a screw-type solid-addition head, and was connected to a KOH-scrubber via PTFE tubing.
• the system was flushed with Argon over 30 min before use.
• Bis(chlorosulfonyl)imide (52.6 g, 243 mmol) was melted in a glovebox and canulated under Argon into the flask, then was pre-heated at about 50°C.
• Anhydrous ammonium chloride 13 g, 243 mmol was loaded into the solid dosing screw-type glass apparatus, and was gradually added over 0.5h under argon stripping and constant stirring.
