Process for producing lithium bis(fluorosulfonyl)imide salt |
| abstract |
The invention relates to a process for producing lithium bis(fluorosulfonyl)imide salt. The present invention discloses a process for producing lithium bis(fluorosulfonyl)imide salt involving the following steps: a) a step of producing bis(chlorosulfonyl)imide Cl-SO2NHSO2-Cl, comprising a step of heating a mixture containing sulfamic acid and chlorosulfonic acid at a temperature T1 higher than 40°C and then adding thionyl chloride, b) a step of reacting the bis(chlorosulfonyl)imide Cl-SO2NHSO2-Cl obtained in step a) with a fluorinating agent of formula (I): NH4F(HF)n(I), in which n is an integer from 0 to 10, in order to form a compound of formula (II), and c) a step of cation exchange in an organic solvent with a lithiated compound to form the lithium bis(fluorosulfonyl)imide salt. |
