Abstract (en)

[origin: WO2019229360A1] The invention relates to a method for producing a lithium bis(fluorosulfonyl)imide salt F-(S02)-NLi-(S02)-F, comprising a step (a) comprising a step of chlorination of sulfamic acid HO-(S02)-NH2 in order to obtain the bis(chlorosulfonyl)imide CI-(S02)-NH-(S02)-CI, said step (a) being carried out in a reactor made of a corrosion-resistant material M3, or in a reactor containing a base layer made of a material M1 coated with a surface layer made of a corrosion-resistant material M2.
