Lithium Bis(trifluoromethanesulfonyl)imide, commonly abbreviated as LiTFSI and identified by CAS number 90076-65-6, is a highly versatile chemical compound with significant industrial applications. Characterized as a white powder, its unique chemical structure and properties make it invaluable in sectors ranging from advanced energy storage to intricate chemical synthesis. As a dedicated manufacturer and supplier, we aim to provide a comprehensive understanding of this important material.

Key Chemical Properties of LiTFSI

LiTFSI is an ionic salt composed of a lithium cation (Li+) and a bis(trifluoromethanesulfonyl)imide anion ([N(SO2CF3)2]-). This anion is known for its exceptional electrochemical stability, thermal stability, and its ability to dissociate readily in various solvents, including water. Its high solubility in water is a distinguishing feature, enabling its use in aqueous electrolytes for lithium-ion batteries. The compound boasts a high molar mass of 287.09 g/mol and a melting point around 236°C, indicating its robustness under various operating conditions. Its excellent ionic conductivity is a primary driver for its widespread adoption in electrochemical devices.

Diverse Applications Across Industries

The applications of LiTFSI are broad and impactful:

  • Electrolytes for Lithium-ion Batteries: This is perhaps its most prominent application. LiTFSI serves as a superior electrolyte salt in lithium-ion batteries, offering enhanced safety and thermal stability compared to other common salts like LiPF6. It is crucial for both organic and aqueous lithium-ion battery systems.
  • Solar Cell Technology: LiTFSI acts as an additive to improve the hole conductivity in dye-sensitized solar cells (DSSCs) and perovskite solar cells (PSCs), thereby increasing their overall energy conversion efficiency.
  • Chemical Synthesis: It functions as a valuable intermediate in various organic synthesis reactions, including the preparation of specialized ionic liquids and in the development of pharmaceutical compounds and dyestuffs.
