Head Shender Iryna O., Registration Date 11-02-2026 Organization Uzhhorod National University State Higher Educational Institution popup.description1 The aim of the work is to develop optimal materials based on compounds with the argyrodite structure Ag6+x(P1-xSix)S5I, which can be used as effective components for renewable energy storage systems popup.description2 Considering the growing demand for secondary energy sources, the project focuses on solving important energy and material science problems, namely the development of technologically simple, environmentally friendly, and highly efficient solid electrolytes. Effective solid electrolytic materials are phases with ionic conductivity. In particular, the research is focused on Ag6PS5I and Ag7SiS5I compounds (by modifying their composition and form), which have high electrical conductivity due to the diffusion of Ag+ ions. The planned research involves studying the relationships between the composition, size, structure, and properties of materials, such as optical, electrical, and mechanical characteristics. Single-crystal materials form the basis of modern high-tech industry, serving as working elements in critically important systems. The physical properties of single crystals, which are a consequence of their ordered structure, make them indispensable for applications where anisotropy of properties or minimization of defects, such as grain boundaries, are key. The research has shown that the solid solutions under study are characterized by a higher σion value and σion/σel ratio at a lower activation energy (Ea=0.137 eV) compared to the initial tetragonal argirides. Based on the analysis of the crystal structure, a mechanism of ion transport in single crystals was proposed. The comprehensive research planned for the project "Solid electrolytes: new-generation materials for environmentally friendly energy solutions" will help identify the most promising samples and determine their potential applications. The main criterion for selecting effective materials is a high value of ionic conductivity compared to the low electronic component - σion>>σel Product Description popup.authors Zhukova Yuliia P.
