Abstract
A method for preparing electrolyte material having a NASICON structure, based on a NaScZr(SiO)(PO) compound where 0≤x<2. The method includes providing an acidic, aqueous solution which, according to a desired stoichiometry, comprises sodium, scandium and zirconium in the form of water-soluble nitrates, acetates or carbonates, and soluble silicates or orthosilicic acids or organic silicon compounds in dissolved form; subsequently adding phosphoric acid or ammonium dihydrogenphosphate or other soluble phosphates, according to the desired stoichiometry, complex zirconium dioxide phosphates forming as colloidal precipitations; and subsequently drying and calcining the mixture.
