IONIC LIQUIDS, METHOD FOR MANUFACTURING THEREOF, AND ELECTROCHEMICAL DEVICES COMPRISING THE SAME

摘要

The present invention concerns ionic liquids comprising at least one pyrazolium cation which are substituted by at least one fluorine atom and at least one anion obtainable from 4-ethoxy- 1,1,1 -trifluoro-3-butene-2-one (ETFBO). The ionic liquids according to the present invention can be used as electrolytes for electrochemical and/or optoelectronic devices.
