HYDROSTRICTIVE MATERIALS FOR ANODES AND CATHODES OF STORAGE BATTERIES BASED ON NIOBATES OF ALKALI AND ALKALINE EARTH METALS
The article presents a study of materials based on sodium and calcium niobates, which have the ability to capture water due to the manifestation of the Hadwell effect. It was found by X- ray diffraction that the process of intercalation of water isaccompanied by a change in the topological characteristics of the crystals - hydrostriction. The established phenomena are of interest not only as catalysts for water decomposition, but also as a basis for the creation of Na-ion storage batteries.
