1-Hexyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, CAS: 380497-19-8

Key Applications

Electrochemical Systems

• Employed as a non‑volatile electrolyte or electrolyte additive in lithium, sodium, and multivalent battery research.
• Supports stable SEI formation and improved cycling behavior in high‑voltage systems due to the TFSI anion’s oxidative stability.
• Used in supercapacitors and electrochemical double‑layer capacitors (EDLCs) for enhanced ionic conductivity and wide operating temperature ranges.
• Serves as a solvent and ion‑transport medium in redox‑active systems and electrodeposition studies.

Materials Science and Thin‑Film Processing

• Utilized in ionic‑liquid gating and electrostatic doping of semiconductors, oxides, and 2D materials.
• Functions as a plasticizer or ionic additive in polymer electrolytes and ionogels.
• Applied in surface modification, nanoparticle stabilization, and template‑directed synthesis where hydrophobic, low‑coordinating ionic environments are required.

Separation Science and Extraction

• Effective in liquid–liquid extraction of metal ions, particularly for hydrophobic or soft‑metal species compatible with TFSI‑based ionic phases.
• Used in chromatographic stationary phase development and supported ionic‑liquid membranes for selective transport of organic or organometallic species.

Thermal and Chemical Processing

• Suitable as a high‑temperature heat‑transfer medium or reaction solvent due to its thermal stability and negligible vapor pressure.
• Applied in catalysis, especially in biphasic or immobilized‑catalyst systems where phase separation and recyclability are important.

Tribology and Lubrication

• Incorporated into advanced lubricants and anti‑wear additives for metal and ceramic interfaces, leveraging the TFSI anion’s ability to form stable boundary layers under load.
