전해액 재료의 특성에 영향을 미치는 잔류 용매를 삭감시킨 N-(플루오로설포닐)-N-(플루오로알킬설포닐)이미드, 디(플루오로설포닐)이미드를 함유하는 전해액 재료를 제공한다. 하기 화학식(1)의 플루오로설포닐이미드염과 전해액 용매를 포함하는 전해액 재료의 제조방법으로써, 플루오로설포닐이미드염과 전해액 용매를 포함하는 용액을 감압 및/또는 가열해서, 플루오로설포닐이미드염의 제조 용매를 휘발시키는 것을 특징으로하는 전해액 재료의 제조방법이다:상기 식에서, R은 불소 또는 탄소 수 1∼6의 불화 알킬기, R는 알칼리 금속 이온을 나타낸다. An electrolytic solution comprising N-(fluorosulfonyl)-N-(fluoroalkylsulfonyl)imide or di(fluorosulfonyl)imide, from which a residual solvent that affects the properties of the electrolyte solution material is reduced, is provided. A method for producing an electrolyte solution material containing fluorosulfonyl imide salt represented by the following general formula (1) and an electrolyte solution preparation solvent comprises decompressing and/or heating a solution containing the fluorosulfonyl imide salt and the electrolyte solution preparation solvent to volatilize a production solvent for the fluorosulfonyl imide salt. In general formula (1), R 1 represents a fluorine atom or a fluorinated alkyl group having 1 to 6 carbon atoms, R 2 represents an alkali metal ion.
