Novel lithium and sodium salts of sulfonamides and bis(sulfonyl)imides: synthesis and electrical conductivity

摘要

The preparation of new electrolytes for application in lithium or sodium batteries is described. Different salts of lithium and sodium sulfonamide and bis(sulfonyl)imide were prepared in good yields. Ionic conductivity measurements were performed on these salts and conductivities of 0.20 to 0.51 mS cm~(-1), comparable to those of Li-TFSI, were obtained. The best conductivity was reached for the Li~+ salt of a bis(sulfonyl)imide bearing CF3 and 4-FC6H4 groups.
