Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI), with the chemical molecular formula of C2F6LiNO4S2, is a white crystalline or powdery organic substance with high electrochemical and thermal stability. As an electrolyte additive, LiTFSI can be applied to various battery systems such as primary lithium batteries, secondary lithium batteries and solid state lithium batteries.
Lithium bis(trifluoromethylsulfonyl)imide (LiTFSI), a key component in the electrolyte of lithium-ion batteries, is known for its excellent thermal and electrochemical stability. Through its unique molecular configuration, this lithium salt builds a solid anion network within the electrolyte, which not only significantly reduces the viscosity of the solution, but also dramatically increases the lithium ion shuttle rate. This property directly translates into high efficiency in the battery charging and discharging process, making LiTFSI ideal for enhancing the overall performance of lithium-ion batteries. Especially in the research and development of solid-state lithium batteries, LiTFSI shows great potential. In addition, it shows highly positive performance in Sodium Metal Batteries (SMBs) research and is expected to drive further innovation in battery technology. However, the performance stability of LiTFSI in complex & systematic environments are the urgent issues to be solved in the current research.
Lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) has begun applications in bulk in new types of batteries such as solid-state lithium-ion batteries, including polymer solid-state batteries, sulfide solid-state batteries and oxide solid-state batteries. LiTFSI has been shown to be useful for improving battery performance, including its role in anode protection, facilitating the ability of fast charging, and promoting high advantage in a wide temperature range. Lithium bis(trifluoromethanesulfonyl)imide is one of the important electrolyte additives for lithium batteries, which can improve the electrochemical stability, cycling performance and conductivity of the electrolyte, and has less corrosive effect on aluminum foil at higher voltages, which can be adapted to increase the energy density of batteries in EV industry.
