Ionic Liquids

A new family of hydrophobic ionic liquids that provide improved thermo-chemical stability and are stable to water and oxygen has been developed by Covalent. Our patented ionic liquid materials are derived from cyclic stabilized organic cations and the conjugate bases of organic superacids. We provide the industry with developmental quantities of these novel materials.

Ionic liquids are liquids with a wide liquidus and temperature range, and no measurable vapor pressure. In the simplest form ionic liquids are binary liquids, composed solely of anions and cations. These materials manifest physiochemical behaviors quite unlike water or organic solvents. They possess high ionic conductivity, high ion concentrations, and excellent oxidative stability making them ideal materials for demanding applications at elevated temperature. Applications benefiting from these materials include power sources (batteries, capacitors, and fuel cells) photovoltaic devices, dye sensitized solar cells, thermal fluids and lubricants.

We offer for evaluation the following ionic liquids in electrochemical (-E) grade:
