Lithium Bis(trifluoromethanesulfonyl)imide, LiTFSI
CAS: 90076-65-6
Lithium bis(trifluoromethanesulfonyl)imide, commonly referred to as LiTFSI, has the chemical formula (CF3SO2)2NLi, formula weight 287.08, appears to be white crystal or powder, with its density 1.33 g/cm3, melting point 236 °C (457°F; 509K). LiTFSI is highly soluble in water. The decomposition point of LiTFSI is as high as 370 degrees Celsius; LiTFSI has excellent chemical stability at high temperatures and will not produce HF even in contact with water; LiTFSI can significantly reduce the risk of decomposition of the electrolyte at high temperature, even if being used simply as an additive.
In the secondary Li-ion battery field, LiTFSI can be used as an additive together with LiPF6-based electrolytes, and is also the main ingredient for LFP and ternary NMC/NCA electrolytes to enhance their conductivity, safety, and life cycle.
In Li-ion polymer batteries, LiTFSI improve the safety and performance of the battery, and can also adapt to ultra-thin and diversified requirements.
In high-performance primary lithium batteries, LiTFSI gives significantly better performance in terms of safety, capacity, and performance in wide range of temperatures than traditional lithium batteries using LiClO.
Lithium bis(trifluoromethanesulfonyl)imide can also be used as catalyst in chemical synthesis.
Poworks manufactures and supplies high-quality lithium bis(trifluoromethanesulfonyl)imide for a variety of applications.
