1-Ethyl-3-methylimidazolium bis(fluorosulfonyl)imide, CAS: 235789-75-0

Key Applications:

Advanced Battery Electrolytes

• Used as a high‑conductivity electrolyte or co‑solvent in lithium‑ion, sodium‑ion, and solid‑state battery systems.
• Enhances SEI formation, thermal stability, and cycle life, particularly in high‑voltage cathode chemistries.
• Supports high‑rate performance due to low viscosity and fast ion transport.

Lithium Metal & Lithium‑Sulfur Systems

• Promotes stable interfaces on lithium metal anodes, reducing dendrite formation.
• Applied in Li–S catholyte formulations to improve sulfur utilization and suppress polysulfide shuttling.

Supercapacitors & Hybrid Capacitors

• Functions as a non‑volatile, high‑conductivity electrolyte for EDLCs and hybrid supercapacitors.
• Enables wide operating voltage windows and improved high‑temperature performance.

Electrodeposition & Surface Engineering

• Serves as a stable medium for metal electrodeposition, including aluminum, magnesium, and rare‑earth metals.
• Used in corrosion‑resistant coatings, nanostructured films, and high‑purity metal processing.

High‑Temperature & High‑Voltage Electrochemistry

• Suitable for high‑temperature fuel cells, redox systems, and electrochemical reactors requiring non‑flammable, thermally robust electrolytes.
• Supports ionic‑liquid‑based redox couples and electrosynthesis under demanding conditions.

Catalysis & Green Chemistry

• Acts as a tunable solvent for acid‑catalyzed reactions, organometallic transformations, and ionic‑liquid biphasic systems.
• Enables halide‑free, low‑volatility, and recyclable reaction media for sustainable processing.

Materials Processing & Nanomaterials

• Used in the synthesis of nanoparticles, nanocomposites, and functional coatings where controlled ion transport and thermal stability are required.
• Supports polymer electrolyte fabrication and ion‑conducting membranes.
