Description

1,3-Bis(Cyanomethyl)Imidazolium Bis(Trifluoromethylsulfonyl)Imide is a specialized ionic liquid compound that serves as a high-performance, non-aqueous electrolyte component and functional material. Its unique structure, combining a dicyanomethyl-functionalized imidazolium cation with a hydrophobic, thermally stable anion, offers exceptional electrochemical stability and low volatility. This product is essential for researchers and manufacturers in advanced battery technologies, particularly for next-generation lithium-ion and lithium-metal batteries, as well as for applications in catalysis, separation science, and as a precursor for advanced polymers.

Application

• Electrolyte Additive/Solvent for Lithium-Ion Batteries: Enhances ionic conductivity, improves thermal stability, and suppresses dendrite formation in high-voltage battery systems.
• Electrolyte for Lithium-Metal Batteries: Used in formulating stable, non-flammable electrolytes to improve cycle life and safety of lithium-metal anodes.
• Catalyst Solvent/Medium: Serves as a green, non-volatile reaction medium for organic synthesis and transition metal catalysis.
• Gas Separation Membranes: Incorporated into polymer matrices to create facilitated transport membranes for CO2 separation and other gas purification processes.
• Polymerizable Ionic Liquid Monomer: Acts as a precursor for synthesizing poly(ionic liquids) with tailored properties for sensors, actuators, or conductive materials.
• Lubricant Additive: Improves tribological properties and reduces wear in advanced lubricants for demanding mechanical systems.
• Analytical Chemistry: Utilized as a stationary phase modifier in chromatography or as a matrix for mass spectrometry.

Quality Control

Our production of 1,3-Bis(Cyanomethyl)Imidazolium Bis(Trifluoromethylsulfonyl)Imide adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity, which is critical for electrochemical performance. All materials are synthesized and handled in controlled environments to minimize metallic and anionic impurities. Certificates of Analysis (COA) are provided with each shipment, detailing key parameters such as assay, water content, halide content, and residual solvent levels. We support customer-specific quality requirements and can provide material compliant with relevant standards for battery materials and advanced chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation. Keep away from strong oxidizing agents.
