Application

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.
