METHOD FOR MANUFACTURING INORGANIC ELECTROLYTE MEMBRANE HAVING IMPROVED COMPACTNESS, COMPOSITION FOR MANUFACTURING INORGANIC ELECTROLYTE MEMBRANE, AND INORGANIC ELECTROLYTE MEMBRANE MANUFACTURED USING SAME

摘要

The present invention relates to a method for manufacturing an inorganic electrolyte membrane and a composition for manufacturing the inorganic electrolyte membrane, the method comprising: (a) a step for mixing primary inorganic particles (having a size of < 50 nm), a dispersant and a solvent and dispersing the primary particles to manufacture a dispersion of secondary inorganic particles having a hydrodynamic diameter using dynamic lighting scattering (DLS) of 120 to 230 nm; (b) a step for adding a binder to the particle dispersion to be mixed; (c) a step for coating and drying the mixed solution of the particle dispersion and the binder to manufacture a green sheet; and (d) a step for firing the green sheet to form an electrolyte membrane.
