NaSO3F, a colorless and transparent liquid, is used as an electrolyte additive in PC solvent systems; Mainly used to optimize the electrochemical performance of electrolytes, enhance battery cycling stability and safety. Its unique fluorosulfonate group can participate in the formation of solid electrolyte interface (SEI), improve sodium ion transport efficiency, suppress side reactions, and is suitable for high-energy density sodium ion battery systems.

Product features:

Enhance ion conductivity: promote sodium ion migration and reduce electrolyte impedance.  

Improving the quality of SEI film: forming a dense and stable SEI layer, reducing electrolyte decomposition.  

High temperature stability: Inhibits electrolyte evaporation and decomposition at high temperatures, improving battery safety.   

Can inhibit dendrite growth: reduce the formation of sodium metal negative electrode dendrites and prolong cycle life.   

Wide compatibility: suitable for various sodium salt electrolyte systems (such as NaPF ₆, NaClO ₄, etc.).
