The properties of orientationally disordered phases and primarily systems based upon alkali metal perchlorates and nitrates studied earlier were reviewed. The crystal-chemical effects (cation and anion size, conduction channel, and free volume of the crystal lattice) upon the conductivity of alkali metal perchlorates were analyzed. Computer simulation of rubidium nitrate was performed by the classical molecular dynamics method. Ion conductivity of hybrid membrane materials with incorporated nanoparticles of inorganic compounds and polyaniline was considered. A new theory of semi-elasticity of membrane pore walls was suggested in order to explain the phenomenon of increasing ion conductivity in such systems. It was assumed that in the low humidity region an additional contribution to the conductivity increase was made by the transfer over the incorporated nanoparticle surface.
