Abstract:
The present invention provides a method for producing low-water-content electrolyte solutions. In particular, the present invention provides a method of removing water from a liquid solution comprising a non-aqueous solvent, a hygroscopic metal salt and water. It also provides a method for producing a low-water content electrolyte solution without isolation of the metal salt. The method of the invention is useful in producing low water content electrolyte solutions for batteries such as lithium- or lithium-ion batteries.

Claim (Index 25):
A method for producing an aprotic electrolyte solution comprising lithium bis(fluorosulfonyl)-imide (\u201cLiFSI\u201d), said method comprising:\n (a) combining (i) hydrogen bis(fluorosulfonyl)imide (\u201cHFSI\u201d), (ii) an aprotic solvent, and (iii) a lithium base under conditions sufficient to produce a solution mixture comprising LiFSI and a vapor comprising water; and (b) removing said vapor from said solution mixture to produce said aprotic electrolyte solution having no more than 1000 ppm of water.
