Typical ionic liquid cations and anions and their abbreviations used in this review. In the IL research community, NTf2 is the common reference for this anion, while in the electrochemical community working with battery electrolytes, TFSI is the more common notation. Taking this into account, throughout the paper we will use both notations to be consistent with the most common usage in the discussed corresponding application.
