POSITIVE ELECTRODE FOR SECONDARY CELL, METHOD FOR MANUFACTURING POSITIVE ELECTRODE FOR SECONDARY CELL, AND WHOLE SOLID SECONDARY CELL

Document Type and Number:

WIPO Patent Application WO/2014/115604

Kind Code:

A1

Abstract:

Provided is a positive electrode for a secondary cell having high capacity retention, a method for manufacturing the positive electrode for a secondary cell, and a whole solid secondary cell provided with the positive electrode. The aforementioned problem is resolved by providing a positive electrode for a secondary cell, characterized in that having a positive electrode active material layer that includes at least a positive electrode active material and a solid electrolyte, wherein the positive electrode for a secondary cell is characterized in that the oil absorbency of the positive electrode active material is 35 to 50 mL per 100 g, the average particle diameter of the solid electrolyte is 1.5 to 2.5 µm, and the positive electrode active material layer is obtained by mixing the positive electrode active material and the solid electrolyte without a solvent and pressure-molding the mixture.
