99% Sodium bis (fluoro sulfonyl) imide NaFSI (F2NNaO4S2) for Battery Research 

Sodium bis (fluoro sulfonyl) imide, NaFSI, (F2NNaO4S2) is a kind of sodium battery electrolyte with good performance. Sodium ion battery is characterized by sufficient raw materials, low cost and better comprehensive performance. The amount of fluorine is greatly reduced as raw materials of NaFSI comparing to NaPF6. The economic benefits for large-scale producting of NaFSI are obvious, due to the abundant supply of raw materials.
