Sulfonimide salts for battery applications

A class of sulfonimide salts for solid-state electrolytes can be synthesized based on successive S.sub.NAr reactions of fluorinated phenyl sulfonimides: Fluorinated Aryl Sulfonimide Tags (FAST). The chemical and electrochemical oxidative stability of these FAST salts as well as other properties like solubility, Lewis basicity, and conductivity can be tuned by introducing different numbers and types of nucleophilic functional groups to the FAST salt scaffold.
