Abstract
A method for producing an ionic liquid electrolyte, such as a spiro-based ionic liquid electrolyte, comprising synthesizing an intermediate spiro-based product and subjecting the intermediate spiro-based product to an ion exchange process to obtain an ionic liquid electrolyte. The resulting ionic liquid electrolyte comprises an ionic liquid salt having a cation of (I). The ionic liquid electrolyte can be used in electrochemical energy storage devices, such as supercapacitors.
