说明

一般說明

Lithiumbis(trifluoromethanesulfonyl)imide (LiTFSI) is an anhydrous lithium salt known for its hydrophilic properties and excellent solubility in water. LiTFSI is often used as an electrolyte salt in lithium-ion batteries and other electrochemical energy storage systems. It helps improve the electrolyte′s conductivity, stability, and safety, thereby enhancing the overall performance of the battery. The hydrophilic nature of LiTFSI enables effective ion transport and enhances the overall electrochemical properties of batteriesProperties of LiTFSI:

• High electrochemical stability
• High lithium-ion conductivity
• Thermal stability
• Hydrophilic nature

應用

Lithium bis(trifluoromethanesulfonyl)imide can be used as:

• An additive in the development of dual-functional separator coating materials. These materials are based on covalent organic frameworks (COFs) and are specifically designed for use in high-performance lithium-selenium sulfide batteries. The Li-SeS₂ battery achieved outstanding performance in terms of energy storage and stability. It exhibited a specific capacity of 844.6 mA h g^-1 at 0.5C and a SeS₂ loading of 2 mg cm^-2.
• As an additive in the electrolyte formulation along with polyethylene oxide for the development of solid-state lithium batteries. LiTFSI enhance the ionic conductivity of the PEO-based electrolyte, which is essential for the efficient transport of lithium ions.
• As a key component in the development of a PEO/LiTFSI-coated polypropylene membrane. This membrane is designed for high-loading lithium–sulfur batteries to enhance battery performance, improve capacity, and extend cycle life.
• As a component in the electrolyte system along with TEMPOL derivatives. The incorporation of LiTFSI in the electrolyte system enhances the stability and achieves an efficiency of 6.16% in solid-state fiber dye-sensitized solar cells.
