An ionic conductor according to the present invention includes an electrolyte salt for ionic conduction, an ionically conducting molecule including a molecular chain which provides an ion conducting pathway and a boroxine ring bonded to the molecular chain and trapping anions resulting from the electrolyte salt, and a structural member for dispersion and immobilization of the ionically conducting molecule and the electrolyte salt therein. The structural material gives the ionic conductor mechanical strength, the ionically conducting molecule provides an ion conducting pathway, and the electrolyte salt gives it ionic conductivity.

Ionically conducting molecule, ionic conductor and process for producing the same

A substrate for an ion conductor includes a polymer or molecule capable of sustaining ion conduction, and a boroxine ring. The above mentioned polymer or molecule participates in and promotes ionic conduction. The boroxine ring is bonded to the above mentioned polymer or molecule, and captures anions resulting from dissolution of a salt. An ion conductor includes the substrate, and a salt combined with the substrate. In the ion conductor, the anions resulting from the salt are captured by the boroxine ring, but the cations resulting therefrom are transported. Thus, ion conduction where the majority of charge is carried by the cations occur. As a result, cation transport numbers far greater than usually observed can be achieved.
