1-Ethyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, CAS: 223436-99-5

Key Applications:

Electrochemical Energy Storage

• Non‑volatile electrolyte component for lithium‑ion, sodium‑ion, and post‑Li batteries requiring enhanced safety and high‑temperature stability.
• Additive or co‑solvent in solid–liquid hybrid electrolytes to improve ionic conductivity and interfacial stability.
• Electrolyte for supercapacitors and hybrid capacitors, especially in high‑voltage or elevated‑temperature environments.

Electrodeposition & Surface Engineering

• Medium for metal electrodeposition (e.g., Al, rare‑earth, transition metals) where moisture‑free, wide‑window electrolytes are required.
• Solvent for nanostructured coatings, corrosion‑resistant films, and high‑purity metal layers.

Thermal & Chemical Process Media

• High‑temperature heat‑transfer or reaction medium due to its thermal stability and negligible vapor pressure.
• Solvent for catalysis, organometallic synthesis, and fluorinated compound processing where inert, non‑coordinating media are preferred.

Materials Science & Polymer Engineering

• Plasticizer or ionic additive in ion‑conducting polymers, gel electrolytes, and membrane materials.
• Component in ionic liquid–polymer composites for flexible electronics, antistatic materials, and dielectric tuning.

Sensors & Electroanalytical Systems

• Electrolyte for amperometric, voltammetric, and impedance‑based sensors requiring stable, non‑aqueous ionic environments.
• Medium for reference electrode development and high‑temperature electroanalytical measurements.

Tribology & Lubrication

• Ionic additive in high‑performance lubricants to reduce wear and friction under extreme thermal or mechanical loads.
• Base fluid for vacuum‑stable or non‑flammable lubrication systems.
