| description | A method for producing lithium difluorophosphate according to an exemplary embodiment of the present invention may comprise the steps of: (S1) reacting a fluorine source and a phosphoryl halide represented by chemical formula 1 below in a first organic solvent; and (S2) reacting the reaction product in step S1, a lithium source, and an oxygen source in a second organic solvent. The fluorine source, the lithium source, and the oxygen source each may have a moisture content of less than 1,000 ppm relative to the weight thereof.
Une méthode de production de difluorophosphate de lithium selon un mode de réalisation donné à titre d'exemple de la présente invention peut comprendre les étapes consistant à : (S1) faire réagir une source de fluor et un halogénure de phosphoryle représenté par la formule chimique 1 ci-dessous dans un premier solvant organique; et (S2) faire réagir le produit de réaction dans l'étape S1, une source de lithium et une source d'oxygène dans un second solvant organique. La source de fluor, la source de lithium et la source d'oxygène peuvent chacune avoir une teneur en humidité inférieure à 1000 ppm par rapport au poids de celle-ci.
본 발명의 예시적인 실시예들에 따른 디플루오로인산 리튬의 제조 방법은, (S1) 불소 소스 및 하기 화학식 1로 표시되는 포스포릴 할라이드를 제1 유기 용매 상에서 반응시키는 단계; 및 (S2) S1 단계의 반응 생성물, 리튬 소스 및 산소 소스를 제2 유기 용매 상에서 반응시키는 단계를 포함할 수 있다. 상기 불소 소스, 상기 리튬 소스 및 상기 산소 소스 각각은, 중량을 기준으로 1,000 ppm 미만의 수분 함량을 가질 수 있다. |
