## Lithium Bis(trifluoromethanesulfonyl)imide (LiTFSI, CAS 90076-65-6): Key Functions and Uses
1. **High-Performance Lithium Battery Electrolyte Salt**
Lithium Bis(trifluoromethanesulfonyl)imide, commonly known as **LiTFSI**, is a widely studied lithium salt for liquid, gel, polymer, and solid-state electrolyte systems. It provides mobile lithium ions for charge transport between battery electrodes.
2. **Lithium-Ion Battery Electrolyte Development**
LiTFSI is used in advanced lithium-ion battery research, including lithium-metal, silicon-anode, lithium–sulfur, and high-energy-density cell designs. Its high solubility and strong ionic dissociation can support effective electrolyte conductivity.
3. **High-Voltage and Thermal-Stability Research**
Compared with some conventional lithium salts, LiTFSI is valued for its favorable thermal stability and broad electrochemical operating range. It is therefore investigated for high-voltage cells, high-temperature operation, and safer next-generation energy-storage technologies.
4. **SEI and Interfacial Film Formation**
LiTFSI can participate in the formation of solid electrolyte interphase (SEI) layers on lithium, graphite, and silicon-based anodes. Properly designed interfacial films may reduce unwanted electrolyte decomposition and improve cycling stability.
5. **Solid-State and Polymer Electrolytes**
LiTFSI is an important salt for polymer electrolytes, including PEO-based systems, gel electrolytes, and composite solid electrolytes. It can improve lithium-ion availability and support research into flexible, nonflammable, and high-performance battery architectures.
6. **Ionic-Liquid and Supercapacitor Research**
LiTFSI is used in ionic-liquid electrolytes, hybrid electrolyte systems, supercapacitors, and other electrochemical devices. Its compatibility with selected ionic liquids and organic solvents makes it useful for studying ion transport, electrochemical stability, and energy-storage performance.
7. **Solar Cells and Advanced Electrochemical Devices**
LiTFSI may serve as a lithium-ion source or electrolyte additive in dye-sensitized solar cells, perovskite-related research, electrochemical sensors, and other functional devices. Application-specific testing is required to confirm compatibility and long-term stability.
8. **Quality, Procurement, and Safety Considerations**
When sourcing Lithium Bis(trifluoromethanesulfonyl)imide 90076-65-6, buyers should verify battery-grade purity, water content, halide and metal impurities, thermal properties, packaging, certificate of analysis, and storage requirements. Useful SEO keywords include **Lithium Bis(trifluoromethanesulfonyl)imide, LiTFSI, CAS 90076-65-6, lithium battery electrolyte, solid-state electrolyte, polymer electrolyte, lithium-metal battery, lithium–sulfur battery, and ionic-liquid electrolyte**.
