Spiro-based ionic liquid electrolyte for low temperature supercapacitors and methods of fabricating same

Abstract

A method for fabricating an ionic liquid electrolyte such as a spiro-based ionic liquid electrolyte, the method has the steps of: synthesizing an intermediate spiro-based product, and applying an ionic exchange process to the intermediate spiro-based product to obtain the ionic liquid electrolyte. The obtained an ionic liquid electrolyte comprising an ionic liquid salt with a cation of: (I) The ionic liquid electrolyte may be used in an electrochemical energy-storage apparatus such as a supercapacitor.
