The most often utilized salt in the preparation of non-aqueous electrolytes for SIBs is sodium hexafluorophosphate (NaPF6). It was selected for its ionic conductivity and SEI formation, as well as the fact that it decomposes into F−, which renders the present aluminium collector inactive. Other salts that have been proposed are mostly sodium counterparts of salts that have been studied in the field of LIBs. sodium bis(trifluoromethanesulfonyl)imide (NaTFSI), sodium perchlorate (NaClO4), sodium tetrafluoroborate (NaBF4), sodium trifluoromethanesulfonate (NaCF3SO3), sodium bis(fluorosulfonyl)imide (NaFSI), sodium bis(trifluoromethanesulfonyl)imide (NaTFSI). Another class of solvents is glymes, which have the general formula CH3O(CH2CH2O)n-CH3. Non-dendritic sodium plating and stripping have been achieved using LEs containing NaPF6 and glymes (Seh et al. 2015).

Sodium tetrafluoroborate decomposes into sodium fluoride and gaseous BF3, the latter catalyzes the formation of ketone groups and carbon double bonds, which cross-link with cellulose enhancing formation of char.

Sulforaphane is synthesized via sonication of thiolane with methyl iodide followed by anionic metathesis with NaBF4 (sodium tetrafluoroborate) in butanol that produce thiolanium tetrafluoroborate. Conversion of thiolanium tetrafluoroborate to 1-azido-(4methylsulfinyl) butane at 60 °C in 16 h via ring opening by SN2 (indicated by TLC). Further, 1-azido-(4methylsulfinyl)butane after the Staudinger reaction converted to Erucin and the oxidation of Erucin in transition metal-free condition (H2O2/glacial acetic acid) to give sulforaphane in racemic form [40] (0.32 g sulforaphane, yield: 91%).
