1-(2-Methoxyethyl)-1-methylpyrrolidinium bis(fluorosulfonyl)imide, CAS: 1235234-47-5

Key Applications:

Advanced Electrolytes

• Serves as a high‑conductivity ionic liquid electrolyte component for lithium, sodium, and multivalent metal batteries.
• Enhances low‑temperature ionic mobility due to the flexible 2‑methoxyethyl side chain.
• Supports high‑voltage cathode chemistries when paired with FSI⁻, which offers fast anion transport and favorable SEI formation.

Capacitors and Energy Storage

• Used in electrochemical double‑layer capacitors (EDLCs) and hybrid capacitors requiring low viscosity and high ionic conductivity.
• Improves cycling stability in devices operating across wide temperature ranges.

Electrodeposition and Metal Processing

• Functions as a non‑volatile, thermally stable medium for controlled metal deposition, especially for reactive metals where traditional solvents are unsuitable.
• Enables smooth, uniform metal films due to the FSI⁻ anion’s favorable coordination behavior.

Organic Synthesis and Catalysis

• Acts as a tunable, polar, aprotic solvent for transition‑metal‑catalyzed reactions.
• Supports high‑selectivity transformations where moisture‑free, thermally robust media are required.

Separation Science

• Utilized in liquid–liquid extraction systems for selective metal ion separation, particularly for rare‑earth and transition‑metal purification.
• Offers improved phase behavior and solvation characteristics due to the ether‑functionalized cation.

Thermal and Chemical Stability Applications

• Suitable for high‑temperature environments where conventional organic solvents degrade.
• Employed in specialty formulations requiring low vapor pressure and strong electrochemical stability.
