Abstract: Provided is an apparatus for producing a non-aqueous electrolytic solution capable of easily performing purification treatment by removal of acidic impurities such as hydrogen fluoride contained in a non-aqueous electrolytic solution.
The apparatus for producing a non-aqueous electrolytic solution comprises an ion exchange unit accommodating a weakly basic anion exchange resin through which an alkali metal salt electrolyte-containing solution having the alkali metal salt electrolyte dispersed in an carbonate ester is passed to obtain the non-aqueous electrolytic solution, wherein the weakly basic anion exchange resin has a styrene-based resin as substrate and an amino group as weakly basic anion exchange group.
