MANUFACTURING METHOD OF DISPERSION LIQUID, MANUFACTURING METHOD OF SHEET, MANUFACTURING METHOD OF SECONDARY BATTERY, SHEET, AND SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2022082413
Kind Code:
A
Abstract:
To provide a manufacturing method of a dispersion liquid in which a solvent does not easily remain, a manufacturing method of a sheet, a manufacturing method of a secondary battery, a sheet, and a secondary battery.SOLUTION: In a manufacturing method of a dispersion liquid, in a preparation step, a solvent having the donor number of less than 1 is prepared, and in a dispersion step, a complex hydride having ionic conductivity is dispersed in the solvent. In a manufacturing method of a sheet, a dispersion liquid containing the solvent having the donor number of less than 1 is applied to a support in a coating step, and the solvent is removed from the dispersion liquid coated on the support in a removing step. A secondary battery includes, in this order, a positive electrode layer, a solid electrolyte layer, and a negative electrode layer, and the solid electrolyte layer is composed of a dispersion liquid from which the solvent has been removed.SELECTED DRAWING: Figure 1
