Provide are an ionic liquid composition for a carbon dioxide separation membrane, a carbon dioxide separation membrane retaining the composition in voids, and a carbon dioxide concentration apparatus provided with the carbon dioxide separation membrane that can be used to separate carbon dioxide from high partial pressure to low partial pressure. The permeability of CO.sub.2 and CO.sub.2 selectivity ratio of the carbon dioxide separation membrane can be improved, and carbon dioxide from high partial pressure to a low partial pressure of 1 kPa or lower can be selectively separated and recycled by using an ionic liquid composition prepared by combining: an ionic liquid (I) that is an aminium having one or more primary or secondary amino groups and an ethylenediamine or propylenediamine backbone in the cation; and an ionic liquid (II) in which the cation has no primary or secondary amino group and the anion is an oxoacid anion.

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.
