Liquid salts – Out of the glove box...

Ionic liquids possess very attractive physico-chemical properties. They enable, for example, electrochemical deposition of highly base metals. The focus of the work at the Fraunhofer IST is hereby directed on the use of strongly eutectic solutions which are inexpensive and non-toxic. The process has been further developed in such a way that it is also possible to use the moisture-sensitive ionic liquids outside of the glove box. Incorporating digital approaches, the process chain is being scaled up on this basis.

...and into industry - Utilization of cost-effective and sustainable electrolytes

Electrochemistry in ionic liquids has a very high potential for the development of new fields, such as the replacement of critical substances and in modern energy storage systems. Simultaneously, the process requirements are exceptionally high. The services offered by the IST include the provision of concepts for the integration of cyberphysical systems and in-process environmental assessment for sustainable process development, optimization and scaling tailored to meet customer requirements. Furthermore, these can be used as (decision) support and for process monitoring.
