Superacids conjugate Brpnsted-Lewis

The anions from conjugate Brpnsted-Lewis superacids represent the core lithium salts used for commercial lithium batteries (i.e., LiPFg and LiBp4). The acidity order determined from QC calculations is as follows HBF4 (287.7) [Pg.21]

Regardless, it is important to keep in mind that superacidity encompasses both Brpnsted and Lewis acid systems and their conjugate acids. The qualitative picture of Lewis acid strengths will be discussed in Section 1.4.7. 

As discussed, superacids, similar to conventional acid systems, include both Brpnsted and Lewis acids and their conjugate systems. Protic (Brpnsted-type) superacids include strong parent acids and the mixtures thereof, whose acidity can be further enhanced by various combinations with Lewis acids (conjugate acids). The following are the most frequently used superacids.
