METHOD OF PRODUCING SOLID ELECTROLYTE RbAgI Russian patent published in 2019 - IPC H01G9/25 C01B9/06 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing solid electrolyte with high ionic conductivity and can be used in electrical engineering and electronics. Method of producing solid RbAg₄I₅ electrolyte includes preparation of a mixture of rubidium and silver iodides in stoichiometric ratio, mechanical treatment of a mixture of iodides in a planetary mill, post-synthetic annealing of the material in an inert atmosphere. Initial mixture of silver and rubidium iodides is subjected to mechanical treatment in a planetary mill in an atmosphere of inert gas under protective illumination for 200-400 hours.

EFFECT: invention improves conductivity of the electrolyte, namely, increases ionic conductivity and reduces electronic conductivity at room temperature and at low temperatures of solid electrolyte RbAg₄I₅.
