Nanoionics: New materials and supercapacitors

The review presents the results of investigations of solid state nanomaterials and nanosystems with fast ion transport developed at the IMT RAS. The concept of a new branch of science, “nanoionics”, is proposed. New optically active physicochemical nanosystems Ag(Cu)I-M, with record high concentrations of rare-earth and transition metals (M) were discovered. The development of a new class of impulse high capacity sub-voltage devices with coherent heterojunctions, “nanoionic supercapacitors”, was initiated within the framework of a new direction, “nanoionics of advanced superionic conductors”. A search for areas of nanoionic device application was made with regard to the development of deep-sub-voltage nanoelectronics and related technologies in the nearest 5–10 years and the creation of high-density digital logics and memory, operating in hybrid nanostructures due to the combination of electron quantum transport and classical ion movement (nanoelionics) in the long future prospect.
