Sodium Bis(fluorosulfonyl)imide Usage And Synthesis

Uses

A highly concentrated electrolyte based on sodium bis(fluorosulfonyl)imide (NaFSI) enables the use of Na metal anodes for room-temperature sodium metal batteries based on a Na3V2(PO4)3 cathode with the charging cut-off voltage of 3.7 V versus Na/Na+[1].
