1-Ethyl-3-methylimidazolium trifluoromethansulfonate, CAS: 145022-44-2

Key Applications:

• Zn–Air Battery Electrolytes

• Functions as a high‑stability ionic liquid electrolyte or co‑solvent for Zn–air systems, leveraging the weakly coordinating OTf⁻ anion to support efficient Zn²⁺ transport.
• Improves zinc plating/stripping behavior, reducing dendritic growth and promoting uniform deposition at the anode.
• Enhances oxygen reduction and evolution kinetics (ORR/OER) at the air cathode by providing a stable, low‑volatility ionic environment.
• Offers wide electrochemical stability windows, enabling higher rechargeability and reduced parasitic reactions in alkaline and hybrid Zn–air architectures.
• Supports water‑in‑ionic‑liquid and hybrid electrolyte formulations, improving carbonation resistance and long‑term cycling performance.
• Useful in research‑grade rechargeable Zn–air cells, flexible Zn–air prototypes, and high‑energy‑density metal–air electrolyte development.
