1-Butyl-3-methylimidazolium tricyanomethanide, CAS: 878027-73-7

Key Applications:

• Electrolytes for High‑Performance Batteries and Supercapacitors

• Serves as a stable electrolyte or co‑solvent in lithium‑ion, sodium‑ion, and dual‑ion battery systems.
• Enhances ionic conductivity and improves SEI formation due to the TCM⁻ anion’s high charge delocalization.
• Used in supercapacitors to increase energy density and widen the operational voltage window.

• Dye‑Sensitized Solar Cells (DSSCs)

• Functions as a low‑volatility electrolyte component, improving ionic mobility and long‑term device stability.
• Supports efficient redox shuttle transport in iodide/triiodide and cobalt‑based systems.

• Catalysis and Organic Synthesis

• Acts as a reaction medium for transition‑metal catalysis, C–C coupling, and nucleophilic substitution reactions.
• Provides enhanced reaction rates and selectivity due to its polarity and ability to stabilize charged intermediates.

• Gas Absorption & Separation

• Demonstrates strong affinity for acidic gases (SO₂, CO₂) due to the electron‑rich TCM⁻ anion.
• Used in tunable IL‑based absorption systems and membrane formulations.

• Electrochemical Sensors

• Incorporated into electrode coatings to improve conductivity and stability in biosensors, redox sensors, and environmental monitoring devices.

• Solvent for Nanomaterials Processing

• Supports dispersion and stabilization of metal nanoparticles, graphene, and carbon nanostructures.
• Enables controlled synthesis of nanomaterials with narrow size distributions.
