Title: Electrolytes containing superhalogens for metal ion batteries

Abstract

Compounds (salts) for use as electrolytes, e.g. in batteries such as Li ion, Na ion and Mg ion batteries are provided. The negative ions (anions) of the compounds are complex molecules containing superhalogens, and thus exhibit improved safety, and yet have electron affinities that are equal to or greater than those of halogens. In addition, the binding energy between Li+ and the anions is relatively small so ions can move easily from one electrode to the other in solutions in which the compounds are dissolved. A further advantage is that the affinity of the electrolyte for water is also relatively low so that batteries in which the electrolytes are used have longer lives than those of the prior art.
