Inflammable, high-purity electrolytes for battery & supercap applications

Increased safety and performance through  ionic liquid electrolytes
Ionic liquids as electrolytes

Safer & more environmentally friendly electrolytes with increased performance. The unique combination of physicochemical properties make ionic liquids ideal candidates for key energy storage applications such as batteries & supercapacitors.

IL properties - competitive electrolytes through

  • high electrochemical stability
  • wide operating voltage window (4.5-6 V)
  • high conductivity
  • negligibile vapor pressure & flammability
  • high thermal stability (up to 300-400°C)
  • tunable solvation properties
  • broad liquid range
  • compatibility with various electrode materials
  • environmental compatibility
  • high tunability of properties by structural variations and usage of IL mixtures


Most astonishing results have been shown in applications such as super-capacitors, Li-ion batteries, dye sensitized solar cells, sensor materials and metal plating processes.

Spotlight on EMIM FSI

Recently, the CBILS®-process for EMIM FSI has been developed and optimized in the kg-scale. The advantages of EMIM FSI compared to other ionic liquid electrolytes are
  •  high electric conductivity (17.5 mS/cm)
  •  low freezing point (-48 °C)
  •  low viscosity (21 mPas @ 20 °C).

The obtained quality of EMIM FSI in lab-scale was remarkable (15 ppm water and a halide content below 5 ppm); the process is ready for scale-up to the ton-scale.

 

REACH registration

An increasing demand for high-purity ionic liquids especially in the electronic and automotive industry induced the upscaling and REACH registration of EMIM-TFSI (REACH registration number: 01-2120825886-41-0000 as well as EMIM-BF4 (REACH registration number: 01-2120086816-43-0000) which enables proionic to produce up to up to 10 t/a. Both substances are available on a ton-scale basis in unique quality.
