✨Product Desctiption

Lithium Bis(fluorosulfonyl)imide (LiFSI) is a high-performance lithium salt widely used in advanced electrolyte systems, especially for next-generation lithium-ion batteries. Compared with conventional lithium salts, LiFSI offers superior ionic conductivity, enhanced thermal stability, and improved electrochemical performance, making it a key material for high-energy-density and long-life battery systems.

🧩 Applications

Lithium Bis(fluorosulfonyl)imide is primarily used in:

  • Lithium-ion battery electrolytes (advanced and high-energy batteries)
  • Electric vehicle (EV) battery systems
  • Energy storage systems (ESS)
  • Lithium metal batteries and solid-state battery research
  • High-performance electrolyte formulations requiring high ionic conductivity and stability

Due to its excellent electrochemical stability and low impedance characteristics, LiFSI helps improve battery cycle life, rate capability, and low-temperature performance. It is increasingly considered as a next-generation alternative to traditional lithium salts in high-end energy storage applications.

🏭 Storage Conditions

To ensure product stability and performance, the following storage conditions are recommended:

  • Store in a cool, dry, and well-ventilated area
  • Keep container tightly closed when not in use
  • Protect from moisture and humidity, as the product is moisture-sensitive
  • Avoid exposure to strong acids, oxidizing agents, and water
  • Recommended storage under inert atmosphere (nitrogen or argon) for high-purity grades
  • Suggested storage temperature: 2–8°C or below room temperature in a dry environment
